Severity ?
6.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H
Summary
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.
