shim: Interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems
A buffer overflow was found in Shim in the 32-bit system. The overflow happens due to an addition operation involving a user-controlled value parsed from the PE binary being used by Shim. This value is further used for memory allocation operations, leading to a heap-based buffer overflow. This fl...

AZL-27559 CVE-2022-28737 affecting package shim for versions less than 15.8-1
There's a possible overflow in handleimage when shim tries to load and execute crafted EFI executables; The handleimage 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...
