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:7 relevant fixed versions and status.

sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user.
