Scientific Linux Security Update : pam on SL6.x, SL7.x i386/x86_64
Medium Nessus Plugin ID 85564
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt was discovered that the _unix_run_helper_binary() function of PAM's unix_pam module could write to a blocking pipe, possibly causing the function to become unresponsive. An attacker able to supply large passwords to the unix_pam module could use this flaw to enumerate valid user accounts, or cause a denial of service on the system.
SolutionUpdate the affected pam, pam-debuginfo and / or pam-devel packages.
