Debian Security Advisory DSA-5280-1 security AT debian.org
https://www.debian.org/security/ Steve McIntyre

- -------------------------------------------------------------------------
Package : grub2
CVE ID : CVE-2022-2601 CVE-2022-3775
Several issues were found in GRUB2's font handling code, which could
result in crashes and potentially execution of arbitrary code. These
could lead to by-pass of UEFI Secure Boot on affected systems.
Further, issues were found in image loading that could potentially
lead to memory overflows.
For the stable distribution (bullseye), these problems have been fixed in
version 2.06-3~deb11u4.
We recommend that you upgrade your grub2 packages.
For the detailed security status of grub2 please refer to its security
tracker page at:
https://security-tracker.debian.org/tracker/grub2
Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
