NVD Description

Note: Versions mentioned in the description apply only to the upstream rhceph/rhceph-7-rhel9 package and not the rhceph/rhceph-7-rhel9 package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT is_pem_format is affected because lazy PEM regular expression backtracks extensively. This occurs when a certificate-like input contains repeated BEGIN markers without a matching END marker. As a result, is_pem_format performs unbounded backtracking while searching for a PEM end marker. Consequently, an attacker can cause intensive CPU consumption. This issue is fixed in version 2.14.0.
