Linux Distros Unpatched Vulnerability : CVE-2022-28737

high Nessus Plugin ID 224652

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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 relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
