EulerOS 2.0 SP10 : shim (EulerOS-SA-2023-1830)

high Nessus Plugin ID 175305

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. (CVE-2023-0464)

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.
