    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.
