Remote code execution

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...

CVE-2023-40547 Shim: rce in http boot support may lead to secure boot bypass

CVE-2023-40547

CVE-2023-40547 affects the shim bootloader (shim and shim-unsigned variants) across multiple platforms. The root cause is that the first-stage UEFI boot loader trusts attacker-controlled values when parsing an HTTP response, enabling a remote code execution via a crafted HTTP request during early...

CVE-2023-40551

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...

shim 缓冲区错误漏洞

shim is a simple HTTP service for SciDB. Shim suffers from a security vulnerability that stems from a remote code execution vulnerability contained in the http startup support, which can be used to bypass the secure startup. An attacker can exploit this vulnerability to execute arbitrary code...

UBUNTU-CVE-2023-40548

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...

CVE-2023-40549

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-2023-40546

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...
