CVE-2011-3149 not yet assigned priority: Debian including 1 source packages (pam), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
The _expand_arg function in the pam_env module (modules/pam_env/pam_env.c) in Linux-PAM (aka pam) before 1.1.5 does not properly handle when environment variable expansion can overflow, which allows local users to cause a denial of service (CPU consumption).
