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...

Important: Red Hat Security Advisory: shim security update

shim: RCE in http boot support may lead to Secure Boot bypass

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...

shim: Out-of-bounds read printing error messages

A flaw was found in Shim when an error happened while creating a new ESL variable. If Shim fails to create the new variable, it tries to print an error message to the user; however, the number of parameters used by the logging function doesn't match the format string used by it, leading to a cras...

shim: Out-of-bounds read in verify_buffer_authenticode() malformed PE file

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...

The vulnerability of the UEFI loader’s shim, related to integer overflow or bypassing, allows an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the UEFI loader Shim is related to buffer overflows in 32-bit systems due to a multiplication operation that involves a user-controllable value analyzed from the binary file PE used by Shim. Exploiting this vulnerability can allow an attacker to compromise the confidentiality...

The vulnerability of the UEFI loader’s shim, related to reading beyond the field, allows a hacker to trigger a system failure.

The vulnerability of the UEFI loader “shim” is related to errors in reading beyond the boundary, due to the lack of proper boundary checking during the loading of the binary PE file. Exploiting this vulnerability can allow an attacker to cause a system failure...

The vulnerability of the UEFI loader’s shim, related to reading beyond the field, allows a hacker to trigger a system failure or disclose protected information.

The vulnerability of the UEFI loader “shim” is related to reading beyond the field boundary. Exploiting this vulnerability can allow an attacker to cause a system failure or disclose protected information...

The vulnerability of the UEFI loader’s shim, related to reading beyond the field, allows an attacker to disclose protected information.

The vulnerability of the UEFI loader “shim” is related to errors in reading data beyond the boundary, when attempting to verify the SBAT information. Exploiting this vulnerability can allow an attacker to disclose the protected information...
