CVE:CVE-2023-40551 vulnerable 2026-06-08 06:11:03.598008 Shim: out of bounds read when parsing mz binaries
MEDIUM (5.1)
A flaw was found in the MZ binary format in Shim. An out-of-bounds read may occur, leading to a crash or possible exposure of sensitive data during the system's boot phase.

CVE:CVE-2023-40550 vulnerable 2026-06-08 06:11:03.596777 Shim: out-of-bound read in verify_buffer_sbat()
MEDIUM (5.5)
An out-of-bounds read flaw was found in Shim when it tried to validate the SBAT information. This issue may expose sensitive data during the system's boot phase.

CVE:CVE-2023-40549 vulnerable 2026-06-08 06:11:03.595419 Shim: out-of-bounds read in verify_buffer_authenticode() malformed pe file
MEDIUM (6.2)
An out-of-bounds read flaw was found in Shim due to the lack of proper boundary verification during the load of a PE binary. This flaw allows an attacker to load a crafted PE binary, triggering the issue and crashing Shim, resulting in a denial of service.

CVE:CVE-2023-40548 vulnerable 2026-06-08 06:11:03.592127 Shim: interger overflow leads to heap buffer overflow in verify_sbat_section on 32-bits systems
HIGH (7.4)
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:CVE-2023-40547 vulnerable 2026-06-08 06:11:03.589227 Shim: rce in http boot support may lead to secure boot bypass
HIGH (8.3)
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.
