EulerOS 2.0 SP9 : shim (EulerOS-SA-2023-2344)

medium Nessus Plugin ID 178064

Synopsis

The remote EulerOS host is missing a security update.

Description

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

 - Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether. 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-2023-0465)

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.
