Overview
Affected versions of this package are vulnerable to Buffer Overflow through the grub_udf_read_block function. An attacker can execute arbitrary code by tricking a user into running grub2 with a specially crafted UDF file system image.
Note:
This is only exploitable if the UDF module is built and used.
Workaround
This vulnerability can be mitigated by not running grub2 in an untrusted environment, specifically with a UDF file system image.
