Openwall GNU/*/Linux Information for VU#405955

util-linux package vulnerable to privilege escalation when "ptmptmp" file is not removed properly when using "chfn" utility


Not Affected

Vendor Statement

Openwall GNU/*/Linux (Owl) is not vulnerable. We're using a version of chfn(1) utility from the shadow suite (with our modifications) rather than one from util-linux. This decision was made during Owl development specifically to ensure compatible password file locking across the system as a whole. Additionally, on Owl, chfn(1) isn't available to regular users by default, although that is a supported owl-control setting.
