CBL Mariner 2.0 Security Update: shim (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 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.
