NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets as root, which might allow local users to gain privileges via unspecified vectors, related to serverloop.c.
