NewStart CGSL MAIN 7.02 : shim Multiple Vulnerabilities (NS-SA-2025-0086)
medium Nessus Plugin ID 237991
Synopsis
The remote NewStart CGSL host is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version MAIN 7.02, has shim packages installed that are affected by multiple vulnerabilities:- 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-2023-40551)
- 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-2023-40550)
- 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 crash under certain circumstances. (CVE-2023-40546)
- 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-2023-40549)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
