Discussion

pam-krb5 Local Privilege Escalation Vulnerability

The 'pam-krb5' library is prone to a local privilege-escalation vulnerability because it fails to properly handle setuid processes.

Local attackers may exploit this issue to gain elevated privileges, which may lead to a complete compromise of the system.

This issue affects pam-krb5 as shipped with Debian, Ubuntu, and Gentoo Linux releases; other versions may also be vulnerable.
