Prior to version 3.21.0, `xf_Pointer_New` frees `cursorPixels` on failure, then `pointer_free` calls `xf_Pointer_Free` and frees it again, triggering ASan UAF. A malicious server can trigger a client‑side use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.","severity":{"version":"4.0","score":7.7,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00484,"percentile":0.41995,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-416"],"published":"2026-01-19T17:15:55Z","modified":"2026-11-03T06:33:01Z","fixes":[{"ecosystem":"Alpine:v3.23","package":"freerdp","fixed_in":["3.22.0-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"freerdp","fixed_in":["3.21.0-r0"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"freerdp3","fixed_in":["3.15.0+dfsg-2.1+deb13u1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"freerdp3","fixed_in":["3.21.0+dfsg-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"freerdp3","fixed_in":["3.5.1+dfsg1-0ubuntu1.4"],"sources":["osv"]},{"ecosystem":"Ubuntu:25.10","package":"freerdp3","fixed_in":["3.16.0+dfsg-2ubuntu0.3"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.23","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.22.0-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.21.0-r0"}]}]},{"source":"osv","ecosystem":"AlmaLinux:9","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-1.el9_7.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:9","package":"freerdp-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-1.el9_7.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:9","package":"freerdp-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-1.el9_7.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:9","package":"libwinpr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-1.el9_7.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:9","package":"libwinpr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-1.el9_7.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:8","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-2.el8_10"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:8","package":"freerdp-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-2.el8_10"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:8","package":"freerdp-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-2.el8_10"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:8","package":"libwinpr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-2.el8_10"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:8","package":"libwinpr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:2.11.7-2.el8_10"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-5.el10_1.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-5.el10_1.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-5.el10_1.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:10","package":"freerdp-server","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-5.el10_1.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:10","package":"libwinpr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-5.el10_1.1"}]}],"bundled":7},{"source":"osv","ecosystem":"AlmaLinux:10","package":"libwinpr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.10.3-5.el10_1.1"}]}],"bundled":7},{"source":"osv","ecosystem":"TuxCare:CentOS:7","package":"freerdp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.1-5.el7_9.tuxcare.els8"}]}],"bundled":5},{"source":"osv","ecosystem":"TuxCare:CentOS:7","package":"freerdp-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.1-5.el7_9.tuxcare.els8"}]}],"bundled":5},{"source":"osv","ecosystem":"TuxCare:CentOS:7","package":"freerdp-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.1-5.el7_9.tuxcare.els8"}]}],"bundled":5},{"source":"osv","ecosystem":"TuxCare:CentOS:7","package":"libwinpr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.1-5.el7_9.tuxcare.els8"}]}],"bundled":5},{"source":"osv","ecosystem":"TuxCare:CentOS:7","package":"libwinpr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.1

Prior to version 3.21.0, a client-side heap buffer overflow vulnerability exists in the ClearCodec bands decode path. When a malicious server sends crafted band coordinates, it allows writes past the end of the destination surface buffer. This can be exploited to trigger a client-side heap buffer overflow, causing a crash (Denial of Service) and potentially leading to heap corruption with the risk of arbitrary code execution, depending on allocator behavior and surrounding heap layout.(CVE-2026-23534)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, the FastGlyph parsing process trusts `cbData`/remaining length but never validates it against the minimum size implied by `cx`/`cy`. A malicious server can exploit this vulnerability to trigger a client-side global heap buffer overflow, causing a crash and resulting in a denial of service.(CVE-2026-23732)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, the `xf_Pointer_New` function frees the `cursorPixels` memory on failure. Subsequently, the `pointer_free` function calls `xf_Pointer_Free`, which attempts to free the same memory again, triggering an AddressSanitizer (ASan) detected use-after-free (UAF). A malicious server can trigger a client-side use-after-free, causing a crash (Denial of Service) and potentially leading to heap corruption with a risk of code execution, depending on allocator behavior and surrounding heap layout.(CVE-2026-23883)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a use-after-free vulnerability exists. Specifically, the deletion of an offscreen bitmap leaves the `gdi-\u0026gt;drawing` pointer referencing freed memory. When subsequent related update packets are processed, this leads to a use-after-free condition. A malicious server can exploit this vulnerability when a client connects, causing a client-side crash (Denial of Service) and potentially leading to heap corruption. Depending on allocator behavior and heap layout, there is a risk of arbitrary code execution.(CVE-2026-23884)\n\nA malicious server can trigger a client‑side heap use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24491)\n\nA malicious server can trigger a client‑side heap use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24675)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, AUDIN format renegotiation frees the active format list while the capture thread continues using audin-\u0026gt;format, leading to a use after free in audio_format_compatible. This vulnerability is fixed in 3.22.0.(CVE-2026-24676)\n\nA malicious server can trigger a client‑side heap buffer overflow, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24679)\n\nA malicious server can trigger a client-side heap use after free, causing a crash (DoS) and potential heap corruption with code-execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24681)\n\nA malicious server can trigger a client‑side heap buffer over flow, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24682)\n\nA malicious server can trigger a client‑side heap use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24683)\n\nA malicious server can trigger a client‑side heap use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-24684)\n\nThis is an out-of-bounds read vulnerability affecting FreeRDP clients. A malicious RDP server can exploit this to:\n\n1. **Information Disclosure**: Read sensitive data from the client\u0026apos;s heap memory\n2. **Denial of Service**: Cause client crashes through memory access violations\n\nThe attack requires user interaction (connecting to a malicious server), but no authentication is needed on the server side.(CVE-2026-25941)\n\nA malicious server can trigger a client-side heap use after free, causing a crash (DoS) and potential heap corruption with code-execution risk depending on allocator behavior and surrounding heap layout.(CVE-2026-25997)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a buffer overread in `freerdp_image_copy_from_icon_data()` (libfreerdp/codec/color.c) can be triggered by crafted RDP Window Icon (TS_ICON_INFO) data. The bug is reachable over the network when a client processes icon data from an RDP server (or from a man-in-the-middle). Version 3.23.0 fixes the issue.(CVE-2026-26271)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `rail_window_free` dereferences a freed `xfAppWindow` pointer during `HashTable_Free` cleanup because `xf_rail_window_common` calls `free(appWindow)` on title allocation failure without first removing the entry from the `railWindows` hash table, leaving a dangling pointer that is freed again on disconnect. Version 3.23.0 fixes the vulnerability.(CVE-2026-26986)\n\nFreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a missing bounds check in `smartcard_unpack_read_size_align()` (`libfreerdp/utils/smartcard_pack.c:1703`) allows a malicious RDP server to crash the FreeRDP client via a reachable `WINPR_ASSERT` → `abort()`. The crash occurs in upstream builds where `WITH_VERBOSE_WINPR_ASSERT=ON` (default in FreeRDP 3.22.0 / current WinPR CMake defaults). Smartcard redirection must be explicitly enabled by the user (e.g., `xfreerdp /smartcard`; `/smartcard-logon` implies `/smartcard`). Version 3.23.0 fixes the issue.(CVE-2026-27015)","status":"published","published":"2026-03-06T11:10:32Z","modified":"2026-08-18T01:19:35.897826477Z","cvss":[{"version":"4.0","score":8.7,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","level":"high"}],"updated_at":"2026-11-02T15:52:45.721983Z"},{"id":"RHSA-2026:2048","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-06T10:08:46Z","modified":"2026-06-30T10:41:28Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:18.983284Z"},{"id":"RHSA-2026:2081","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-06T10:08:49Z","modified":"2026-06-30T10:42:10Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:18.983284Z"},{"id":"RHSA-2026:2222","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-09T10:05:40Z","modified":"2026-06-30T10:43:02Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:18.983284Z"},{"id":"RHSA-2026:2736","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-17T10:12:32Z","modified":"2026-06-30T10:46:35Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:19.449341Z"},{"id":"RHSA-2026:2770","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-17T10:12:40Z","modified":"2026-06-30T10:46:45Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:19.449341Z"},{"id":"RHSA-2026:2824","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-18T10:10:59Z","modified":"2026-06-30T10:47:44Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:19.449341Z"},{"id":"RHSA-2026:2952","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-19T10:26:22Z","modified":"2026-06-30T10:48:14Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:19.449341Z"},{"id":"RHSA-2026:3037","title":"Red Hat Security Advisory: freerdp security update","status":"published","published":"2026-02-23T10:05:14Z","modified":"2026-06-30T10:48:43Z","cvss":[{"version":"3.1","score":7.6,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H","level":"high"}],"updated_at":"2026-11-02T15:53:19.963895Z"},{"id":"RLSA-2026:2048","title":"Important: freerdp security update","description":"FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license.
