Kerentanan Out-of-bounds Write pada redhat shim. Skor CVSS 3.1 7.8 (High) menurut NVD.

Deskripsi (NVD)

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.
