Package : grub2 Version : 2.06-3~deb10u3 CVE ID : CVE-2022-2601 CVE-2022-3775 Debian Bug : 1024617 Zhang Boyang reported that the grub2 update released as DLA 3190-1 did not correctly apply fixes for CVE-2022-2601 and CVE-2022-3775. Updated packages are now available to address this issue. For reference the original advisory text follows. 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 Debian 10 buster, these problems have been fixed in version 2.06-3~deb10u3. 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 LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEERkRAmAjBceBVMd3uBUy48xNDz0QFAmOUQaVfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldDQ2 NDQ0MDk4MDhDMTcxRTA1NTMxRERFRTA1NENCOEYzMTM0M0NGNDQACgkQBUy48xND z0QJ1w/7BOI/A+6osMOy2hFRpRQfAZqaDdllU57aRvaQ8JEm5Ee/28XmGro6zqwz AiPZutvEg+0VRWiCTyln+2Myu/aBmOJGTuJiqqdIMroUnH9u6jGEZ3u0/8qtyLG/ xOVX8UgjXdjaMd7uXxbuERhG+lJXbSqN1vv6ZXDIsac1+lu4jrK+xXJ/E1JVVkUm GRJ2xr24/0ZFoD+v5tnujr3f2K0zeIV1/tRi6wjrM/2WGVJCbjjlnPTkhQtfqbHO 3shsf1tBzXgfKbOk1vWZV72WELJcZbx1T3zbOhyRzvZfT22gJfSb8N5WCBxMude6 KpsvUj0AxiTkC9RI/OhIC+gJ2dD+p9afIPBljRoYR4dEKXV64Fi68VLvBDwKHG3R YBpwF7WZCzfHUeFYcDrvKK1g9YzuXmtgvX155brSUTR5UgMIzycoTmftZ829+EZD I/uThildOoqAGZzSH8Nb/5Ot6SVxlHCWhBmCfZ1QgUxOE6o6n1wx0gU+LHgAOnJb E6OMo5Ioj7KMRhWotLFafl9MlOvL2rESIJtY5CArIkmxtRwpmUWch8M0Tk+j7cmL tVM9OO/jqsCM3HBhvfJOu2FNxX/i6WmJEbSrqTfYe0zHB8PV3+PUdlajOXLK3TZ8 NyrSoZwBWxfNSJnjx6VMe5rz5E/E1ON6mU3Ave36QFKLyFZv4vo= =YrkQ -----END PGP SIGNATURE-----
