Package : libapache-mod-dav
Vulnerability : null pointer dereference
Problem-Type : remote
Debian-specific: no
CVE ID : CAN-2004-0809

Julian Reschke reported a problem in mod_dav of Apache 2 in connection with a NULL pointer dereference. When running in a threaded model, especially with Apache 2, a segmentation fault can take out a whole process and hence create a denial of service for the whole server.

For the stable distribution (woody) this problem has been fixed in version 1.0.3-3.1.

For the unstable distribution (sid) this problem has been fixed in version 1.0.3-10 of libapache-mod-dav and in version 2.0.51-1 of Apache 2.

We recommend that you upgrade your mod_dav packages.
