How to fix?

Upgrade SLES:15.4 libopenssl3 to version 3.0.1-150400.4.14.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libopenssl3 package and not the libopenssl3 package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

If an X.509 certificate contains a malformed policy constraint and policy processing is enabled, then a write lock will be taken twice recursively. On some operating systems (most widely: Windows) this results in a denial of service when the affected process hangs. Policy processing being enabled on a publicly facing server is not considered to be a common setup.

Policy processing is enabled by passing the -policy&#39; argument to the command line utilities or by calling the X509_VERIFY_PARAM_set1_policies()' function.

Update (31 March 2023): The description of the policy processing enablement was corrected based on CVE-2023-0466.
