If an attacker underflows the 'num' parameter to memcpy(), this vulnerability could lead to undefined behavior such as writing to out-of-bounds memory and potentially remote code execution. Furthermore, this memcpy() implementation allows for program execution to continue in scenarios where a segmentation fault or crash should have occurred. The dangers occur in that subsequent execution and iterations of this code will be executed with this corrupted data.","status":"published","published":"2020-04-01T22:15:00Z","modified":"2026-04-22T12:43:02.085474Z","cvss":[{"version":"3.0","score":8.1,"vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"high"},{"version":"3.1","score":8.1,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","level":"high"}],"updated_at":"2026-11-02T15:54:25.179924Z"},{"id":"DLA-3152-1","title":"glibc - security update","status":"published","published":"2022-10-17T00:00:00Z","modified":"2026-03-09T01:21:26.95838Z","updated_at":"2026-11-02T15:46:11.189256Z"},{"id":"MGASA-2021-0053","title":"Updated glibc packages fix security vulnerability","description":"Security fixes:\n- fix buffer overrun in EUC-KR conversion module [bz #2497] (CVE-2019-25013)\n- arm: CVE-2020-6096: Fix multiarch memcpy for negative length [BZ #25620]\n- arm: CVE-2020-6096: fix memcpy and memmove for negative length [BZ #25620]\n- iconv: Fix incorrect UCS4 inner loop bounds [BZ #26923] (CVE-2020-29562)\nother upstream fixes:\n- libio: Disable vtable validation for pre-2.1 interposed handles [BZ #25203]\n- string.h: Define __CORRECT_ISO_CPP_STRING_H_PROTO for Clang [BZ #25232]\n- misc/test-errno-linux: Handle EINVAL from quotactl\n- nss_compat: internal_end*ent may clobber errno, hiding ERANGE [BZ #25976]\n- Fix avx2 strncmp offset compare condition check [BZ #25933]\n- AArch64: Align ENTRY to a cacheline\n- AArch64: Add optimized Q-register memcpy\n- AArch64: Improve backwards memmove performance\n- AArch64: Rename IS_ARES to IS_NEOVERSE_N1\n- AArch64: Increase small and medium cases for __memcpy_generic\n- AArch64: Improve integer memcpy\n- AArch64: Use __memcpy_simd on Neoverse N2/V1\n- AArch64: Fix DT_AARCH64_VARIANT_PCS handling [BZ #26798]\n- AArch64: fix stack missing after sp is updated\n- x86-64: Avoid rep movsb with short distance [BZ #27130]\n- x86: Assume --enable-cet if GCC defaults to CET [BZ #25225]\n- x86: Check IFUNC definition in unrelocated executable [BZ #20019]\n- x86: Set header.feature_1 in TCB for always-on CET [BZ #27177]\n- Fix parsing of /sys/devices/system/cpu/online [BZ #25859]\n- Use O_CLOEXEC in sysconf [BZ #26791]\n","status":"published","published":"2021-01-24T00:36:09Z","modified":"2026-04-16T04:43:39.148387396Z","updated_at":"2026-11-02T15:49:41.509337Z"},{"id":"openSUSE-SU-2024:10792-1","title":"glibc-2.34-1.2 on GA media","description":"These are all security issues fixed in the glibc-2.34-1.2 package on the GA media of openSUSE Tumbleweed.","status":"published","published":"2024-06-15T00:00:00Z","modified":"2026-02-04T03:52:58.912445Z","updated_at":"2026-11-02T16:58:34.487567Z"},{"id":"USN-4954-1","title":"glibc vulnerabilities","description":"Jason Royes and Samuel Dytrych discovered that the memcpy()\nimplementation for 32 bit ARM processors in the GNU C Library contained\nan integer underflow vulnerability.
