AZL-96876 CVE-2026-75900 affecting package swtpm 0.8.1-5

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...

CVE-2026-75900

swtpm's SWTPM_NVRAM_CheckHeader() validates buffer length against sizeof(pointer) instead of sizeof(struct), allowing an undersized buffer to pass and cause a 2-byte heap overread (6 bytes on 32-bit). Impact: daemon termination and heap data leakage to logs. Red Hat reports no mitigation; fixed i...

Astra Linux – Vulnerability in Botan

Botan is a C++ cryptography library. Starting from version 2.3.0 and before version 3.11.0, during SM2 decryption, the code responsible for checking the authentication code value C3 failed to verify that the encoded value had the expected length before comparison. An invalid ciphertext could lead...

Astra Linux – Vulnerability in libpng1.6

LIBPNG is a reference library used in applications that read, create, and manipulate PNG Portable Network Graphics raster image files. From version 1.6.26 to 1.6.53, there was an integer truncation in the libpng simplified write API functions pngwriteimage16bit and pngwriteimage8bit, which caused...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, there was a heap buffer over-read vulnerability in the DJVU image format handler.

CVE-2026-19082 Imager versions from 0.45_02 before 1.034 for Perl may expose adjacent heap bytes via strlen() over-read from zero-count ASCII EXIF entries in copy_string_tags

Imager versions from 0.4502 before 1.034 for Perl may expose adjacent heap bytes via strlen over-read from zero-count ASCII EXIF entries in copystringtags. copystringtags computes an ASCII EXIF tag's length as entry-size - 1 to strip the trailing NUL. A zero-count ASCII entry sets entry-size to 0...
