CBL Mariner 2.0 Security Update: shim / shim-unsigned-aarch64 (CVE-2022-28737)

high Nessus Plugin ID 207023

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of shim / shim-unsigned-aarch64 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-28737 advisory.

- There's a possible overflow in handle_image() when shim tries to load and execute crafted EFI executables;
The handle_image() function takes into account the SizeOfRawData field from each section to be loaded. An attacker can leverage this to perform out-of-bound writes into memory. Arbitrary code execution is not discarded in such scenario. (CVE-2022-28737)

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

Solution

Update the affected packages.
