NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-keycat-debuginfo package and not the openssh-keycat-debuginfo package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used.
