How to fix?

Upgrade SLES:15.5 389-ds to version 2.2.10~git255.752643c78-150500.3.48.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream 389-ds package and not the 389-ds package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A flaw was found in 389 Directory Server. The ldap_utf8prev() function reads bytes before the start of a buffer without bounds checking, causing a heap buffer over-read in string filter parsing that may influence internal filter processing behavior.
