NVD Description

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

ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.)
