Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3312 advisory.

- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3312-1 [email protected] https://www.debian.org/lts/security/ Emilio Pozuelo Monfort February 08, 2023 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

Package : shim Version : 15.7-1~deb10u1

This release fixes various issues in shim bootloader and updates it to a supported version. Older versions of the shim may eventually be blocked by Secure Boot, so it is strongly advised for Secure Boot enabled systems to upgrade to this newer version to keep the system bootable.

Additionally, this update blocks old, insecure versions of GRUB. Thus an update to a signed GRUB 2.06-3~deb10u3 package as released in DLA 3190-2 must be in place prior to updating the shim packages.

For Debian 10 buster, this problem has been fixed in version 15.7-1~deb10u1.

We recommend that you upgrade your shim packages.

For the detailed security status of shim please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/shim

Solution

Upgrade the shim-helpers-amd64-signed-template packages.
