EulerOS 2.0 SP9 : shim (EulerOS-SA-2024-1518)

high Nessus Plugin ID 193012

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the shim package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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-2023-40547)

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected shim packages.
