Package        : libapache-mod-python
Vulnerability  : denial of service
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2003-0973
Debian bug     : 222828

The Apache Software Foundation announced that some versions of
mod_python contain a bug which, when processing a request with a
malformed query string, could cause the corresponding Apache child to
crash.  This bug could be exploited by a remote attacker to cause a
denial of service.

For the current stable distribution (woody) this problem has been
fixed in version 2:2.7.8-0.0woody2.

For the unstable distribution (sid), this problem has been fixed in
version 2:2.7.10-1.

We recommend that you update your libapache-mod-python package.
