Package : libapache2-mod-auth-pgsql
Vulnerability : format string vulnerability
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2005-3656
Debian Bug : 307852

iDEFENSE reports that a format string vulnerability in mod_auth_pgsql, a
library used to authenticate web users against a PostgreSQL database,
could be used to execute arbitrary code with the privileges of the httpd
user.

The old stable distribution (woody) does not contain
libapache2-mod-auth-pgsql.

For the stable distribution (sarge) this problem has been fixed in
version 2.0.2b1-5sarge0.

For the unstable distribution (sid) this problem will be fixed shortly.

We recommend that you upgrade your libapache2-mod-auth-pgsql package.
