Title
Shim: interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems
Summary
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 flaw causes memory corruption and can lead to a crash or data integrity issues during the boot phase.

CVE-2023-40547 (GCVE-0-2023-40547)
Vulnerability from nvd – Published: 2024-01-25 15:54 – Updated: 2025-11-20 07:24
VLAI?
Title
Shim: rce in http boot support may lead to secure boot bypass
Summary
A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully.

CVE-2022-28737 (GCVE-0-2022-28737)
Vulnerability from nvd – Published: 2023-07-20 00:26 – Updated: 2024-10-22 13:17
VLAI?
Title
There's a possible overflow in handle_image() when shim tries to load and execute crafted EFI executables
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.
Severity ?
6.5 (Medium)

Title
Shim: interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems
Summary
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 flaw causes memory corruption and can lead to a crash or data integrity issues during the boot phase.
Severity ?

CVE-2023-40547 (GCVE-0-2023-40547)
Vulnerability from cvelistv5 – Published: 2024-01-25 15:54 – Updated: 2025-11-20 07:24

Title
Shim: rce in http boot support may lead to secure boot bypass
Summary
A remote code execution vulnerability was found in Shim. The Shim boot support trusts attacker-controlled values when parsing an HTTP response. This flaw allows an attacker to craft a specific malicious HTTP request, leading to a completely controlled out-of-bounds write primitive and complete system compromise. This flaw is only exploitable during the early boot phase, an attacker needs to perform a Man-in-the-Middle or compromise the boot server to be able to exploit this vulnerability successfully.

CVE-2022-28737 (GCVE-0-2022-28737)
Vulnerability from cvelistv5 – Published: 2023-07-20 00:26 – Updated: 2024-10-22 13:17
VLAI?
Title
There's a possible overflow in handle_image() when shim tries to load and execute crafted EFI executables
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.
Severity ?
6.5 (Medium)
