Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It’s possible to cause the allocation length to overflow with a specially crafted tar file, resulti...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2. When reading the name of a symbolic link from a UFS filesystem, grub2 fails to validate the string length provided as input. This lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and potentially allowing an attacker to...
