|Summary:||The remote host is missing an update for the 'pam'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'pam'
package(s) announced via the referenced advisory.
Pluggable Authentication Modules (PAM) provide a system whereby
administrators can set up authentication policies without having to
recompile programs to handle authentication.
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)
Red Hat would like to thank Sebastien Macke of Trustwave SpiderLabs for
reporting this issue.
All pam users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
pam on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Server (v. 7),
Red Hat Enterprise Linux Workstation (v. 6)
Please Install the Updated Packages.
