Synopsis
========
Format string vulnerabilities in mod_auth_pgsql may lead to the
execution of arbitrary code.
Background
==========
mod_auth_pgsql is an Apache2 module that allows user authentication
against a PostgreSQL database.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-www/mod_auth_pgsql < 2.0.3 >= 2.0.3
Description
===========
The error logging functions of mod_auth_pgsql fail to validate certain
strings before passing them to syslog, resulting in format string
vulnerabilities.
Impact
======
An unauthenticated remote attacker could exploit these vulnerabilities
to execute arbitrary code with the rights of the user running the
Apache2 server by sending specially crafted login names.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All mod_auth_pgsql users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-www/mod_auth_pgsql-2.0.3"
