Versions prior to 3.25.0 have an off-by-one in the path traversal filter in `channels/drive/client/drive_file.c`. The `contains_dotdot()` function catches `../` and `..\\` mid-path but misses `..` when it's the last component with no trailing separator. A rogue RDP server can read, list, or write files one directory above the client's shared folder through RDPDR requests. This requires the victim to connect with drive redirection enabled.

update for freerdp","description":"This update for freerdp fixes the following issues:\n\n- CVE-2026-27951: 32-bit system denial of service via endless blocking loop in `Stream_EnsureCapacity` (bsc#1258939).\n- CVE-2026-33952: client denial of service via unvalidated authentication length field (bsc#1261196).\n- CVE-2026-33977: client denial of service via malformed IMA ADPCM audio data (bsc#1261198).\n- CVE-2026-33982: heap buffer overread in `winpr_aligned_offset_recalloc()` can lead to undefined behavior\n  (bsc#1261222).\n- CVE-2026-33983: improper error handling can lead to use of incorrect shift exponent, undefined behavior and an 80\n  billion iteration loop (bsc#1261200).\n- CVE-2026-33984: heap buffer overflow allows arbitrary code execution via crafted pixel data (bsc#1261211).\n- CVE-2026-33985: heap out-of-bounds read can leak sensitive data when pixel data is rendered to screen (bsc#1261217).\n- CVE-2026-33986: heap out-of-bounds write due to H.264 YUV buffer dimension desync (bsc#1261223).\n- CVE-2026-33987: heap out-of-bounds write due to persistent cache `bmpSize` desync (bsc#1261226).\n- CVE-2026-33995: double-free in `kerberos_AcceptSecurityContext()` and `kerberos_InitializeSecurityContextA()` can\n  lead to crash during NLA connection teardown with a failed authentication attempt (bsc#1261227).\n- CVE-2026-40033: heap buffer overflow in `gdi_CacheToSurface` allows attackers to cause a denial of service or achieve\n  remote code execution (bsc#1266317).\n- CVE-2026-40254: off-by-one error in `contains_dotdot()` allows for drive channel path traversal (bsc#1262743).\n- CVE-2026-44420: heap buffer overwrite can be triggered in server-side clipboard channel when a malicious client sends\n  a `CB_CLIP_CAPS` PDU with a too-small `capabilitySetLength` (bsc#1267008).\n- CVE-2026-44421: improper validation in `gdi_CacheToSurface` can lead to a heap buffer overwrite client when an RDP\n  server sends crafted RDPGFX PDUs (bsc#1267009).\n- CVE-2026-44422: improper memory management can lead to heap use-after-free/double-free in a client's RDPEAR\n  authentication-redirection path (bsc#1267010).\n- CVE-2026-45700: data check bypass when decoding RLE planar data can lead to an out-of-bounds heap write\n  (bsc#1267011).\n- CVE-2026-56297: improper synchronization of `channel_callback` access can lead to use-after-free in\n  `dvcman_channel_close` and `dvcman_call_on_receive` triggered by a malicious RDP server (bsc#1271071).\n- CVE-2026-57156: integer overflow in `update_read_delta_points` allows malicious RDP peers to cause a heap buffer\n  overflow (bsc#1271303).\n- CVE-2026-57157: 2-byte heap out-of-bounds read via attacker-supplied MS-RDPECAM `DeviceName` and `VirtualChannelName`\n  fields (bsc#1271304).\n- CVE-2026-57158: incomplete fix for CVE-2026-23530 in `planar_decompress_plane_rle_only` allows a malicious RDP server\n  to trigger a one byte buffer overflow via a truncated `RDPGFX_CMDID_WIRETOSURFACE_1` planar payload
