Astra Linux – Vulnerability in grub2

A flaw was discovered in the HFS filesystem. When reading the name of an HFS volume during the grubfsmount function, the HFS filesystem driver uses the user-provided volume name as input without properly verifying the length of that name. This issue may lead to a heap-based out-of-bounds write...
