In the Linux kernel, the following vulnerability has been resolved: crypto: ccp – Fix for “off-by-one” issue in snpfilterreservedmemregions Sashiko notes: Regarding the bounds check in snpfilterreservedmemregions, which is called via walkiomemresdesc: Does the check ensure that if...

Astra Linux – Vulnerability in gnutls28

A heap-buffer-overflow off-by-one flaw was discovered in the GnuTLS software during the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds OOB NULL pointer write, resulting in memory corruption a...

Astra Linux – Vulnerability in glibc

A flaw was discovered in glibc. A “off-by-one” buffer overflow and underflow in the getcwd function may lead to memory corruption when the size of the buffer is exactly 1. A local attacker who can control the input buffer and the size passed to getcwd in a setuid program could exploit this flaw t...
