Astra Linux – Vulnerability in zlib, libz-mingw-w64

Zlib versions up to 1.2.12 have a heap-based buffer over-read or buffer overflow issue in the inflate function within inflate.c, due to a large gzip header extra field. NOTE: Only applications that call inflateGetHeader are affected. Some common applications bundle the affected Zlib source code,...

Astra Linux – Vulnerability in libxmltok

In libexpat before version 2.2.8, crafted XML inputs could trick the parser into switching from DTD parsing to document parsing too early. A consecutive call to XMLGetCurrentLineNumber or XMLGetCurrentColumnNumber would then lead to a heap-based buffer overflow...

In Netwide Assembler NASM 2.15rc0, a heap-based buffer over-read occurs due to a malicious .asm file during the call to settextfree from expandonesmacro in asm/preproc.c...

SUSE CVE-2026-75900

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function. The entry guard checks the buffer length against sizeofbh, where bh is a pointer, instead of sizeofbh, the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overre...
