Package : shim Version : 15.8-1~deb10u1 CVE ID : CVE-2023-40546 CVE-2023-40547 CVE-2023-40548 CVE-2023-40549 CVE-2023-40550 CVE-2023-40551 Debian Bug : 1046268 1069054

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.

For Debian 10 buster, this problem has been fixed in version 15.8-1~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

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

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