CVE-2011-3149

Publication date 24 October 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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).
