CVE-2026-106574 1 Imagemagick 1 Imagemagick 2026-10-21 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31, a client connected to the distributed pixel cache server can send crafted pixel data that triggers an integer-size calculation error and a heap buffer overwrite, crashing the server. This issue is fixed in version 7.1.2-31.
CVE-2026-83867 1 Microsoft 23 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 20 more 2026-10-21 7.8 High
Heap-based buffer overflow in Windows Push Notifications allows an authorized attacker to elevate privileges locally.
CVE-2026-111441 1 Opengauss-server 1 Opengauss-server 2026-10-21 8.1 High
在 openGauss-server 的 src/gausskernel/cbb/utils/hll/hll.cpp 中,内置函数 HllObjectUnpack() 存在长度校验缺陷。该函数从用户提供的 packed HLL 解析 lenUsed 与 lenTotal 后,仅检查输入长度足以覆盖 HLL_HEAD_SIZE + lenUsed,随后按 lenTotal 分配缓冲区、按 lenUsed 调用 memcpy_s() 拷贝输入,既未校验 lenTotal >= lenUsed,也将 memcpy_s() 目标大小写成 lenUsed 而非实际分配的 lenTotal,导致安全拷贝无法拦截越界写。hll_in()、hll_print()、hll_cardinality() 等 SQL 入口会走同一解包路径。因此,普通数据库连接用户只需构造 lenTotal 小于 lenUsed 的畸形 packed HLL(例如经 ::hll 进入 hll_in()),即可触发服务端堆越界写,存在内存破坏风险。此问题随 packed HLL 解包函数 HllObjectUnpack() 进入代码,v2.1.0 起即存在。受影响版本包括 2.1.0、3.0.x、3.1.x、5.0.x、5.1.0、6.0.x,以及 7.0.0-RC1、7.0.0-RC2、7.0.0-RC3。该问题已在 7.0.0-LTS 版本修复,通过在 HllObjectUnpack() 中补齐 lenUsed <= lenTotal 校验,并将 memcpy_s() 的目标大小改为实际分配的 lenTotal。修复 PR 见 https://gitcode.com/opengauss/openGauss-server/pull/9380 。
CVE-2026-112280 1 Nkoriyama 1 Aribb24 2026-10-21 6.1 Medium
libaribb24 (aribb24) through 1.0.3 contains a heap-based buffer overflow vulnerability in src/parser.c that allows attackers to corrupt heap memory via an oversized caption data unit. Attackers can supply a crafted caption PES packet in a media file or broadcast stream, processed through arib_parse_pes(), to crash FFmpeg or VLC and possibly corrupt further memory.
CVE-2026-70106 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-21 7.8 High

CVE-2026-114045 1 Freerdp 1 Freerdp 2026-10-21 8.8 High
FreeRDP before 3.32.1 contains a heap-based buffer overflow in the server-side rdpsnd channel because an integer wraparound in rdpsnd_server_select_format() DVI_ADPCM block-alignment arithmetic bypasses validation. A malicious RDP client can send two SNDC_FORMATS PDUs with an nBlockAlign too small for nChannels, causing an unbounded heap write during server audio playback, potentially enabling code execution.
CVE-2026-83881 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-21 7.8 High

CVE-2026-83895 1 Microsoft 20 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 17 more 2026-10-21 6.8 Medium
Heap-based buffer overflow in Windows Win32 Kernel Subsystem allows an unauthorized attacker to elevate privileges with a physical attack.
CVE-2026-84268 1 Redhat 8 Enterprise Linux, Enterprise Linux Eus, Rhel Aus and 5 more 2026-10-21 8.8 High
A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution.
CVE-2026-97763 1 Microsoft 12 365 Apps, Microsoft 365, Microsoft Office Ltsc 2021 and 9 more 2026-10-20 8.8 High
Heap-based buffer overflow in Microsoft Office Excel allows an unauthorized attacker to execute code over a network.
