Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the BFS parser. An attacker can leak sensitive data or cause a crash by supplying a specially crafted or corrupted BFS filesystem image.
Note:
This is only exploitable if the attacker can trick a user into running grub2 with the malicious BFS file system image.
Workaround
This vulnerability can be mitigated by not running grub2 in an untrusted environment, specifically with a BFS file system image.
