Synopsis
========
Vulnerabilities in PAM-MySQL can lead to a Denial of Service, making it
impossible to log into a machine.
Background
==========
PAM-MySQL is a PAM module used to authenticate users against a MySQL
backend.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 sys-auth/pam_mysql < 0.7_rc1 >= 0.7_rc1
Description
===========
A flaw in handling the result of pam_get_item() as well as further
unspecified flaws were discovered in PAM-MySQL.
Impact
======
By exploiting the mentioned flaws an attacker can cause a Denial of
Service and thus prevent users that authenticate against PAM-MySQL from
logging into a machine. There is also a possible additional attack
vector with more malicious impact that has not been confirmed yet.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All PAM-MySQL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-auth/pam_mysql-0.7_rc1"
