--

It 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. (CVE-2015-3238)
