The remote host is missing an update to libapache2-mod-auth-pgsql announced via advisory DSA 935-1. 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. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20935-1
