How to fix?

Upgrade SLES:15.5 bind-doc to version 9.16.50-150500.8.41.1 or higher.

NVD Description

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

An attacker who knows (or guesses) that a resolver uses RPZ with wildcard CNAME policies can craft query names long enough to trigger a NAMETOOLONG error condition during RPZ processing. This is not handled correctly and may lead to defeating the RPZ rule. It also may lead to an unexpected exit of the BIND 9 software. This issue affects BIND 9 versions 9.16.0 through 9.18.50, 9.20.0 through 9.20.24, 9.21.0 through 9.21.23, 9.16.8-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.24-S1.
