Description Jan Lieskovsky 2011-02-27 15:01:38 UTC

A NULL pointer dereference flaw was found in the way mod_dav_svn,
Apache httpd module for Subversion server, processed requests to
lock working copy paths in the repository, when particular Subversion
client, requesting the lock, was not previously authenticated to 
the Subversion server. A remote attacker could use this flaw
to cause a denial of service (crash of particular httpd thread,
serving the request).

Acknowledgements:

Red Hat would like to thank Hyrum Wright of the Apache Subversion project
for reporting this issue. Upstream acknowledges Philip Martin, WANdisco, Inc. as the original reporter.

Comment 1 Jan Lieskovsky 2011-02-27 15:06:02 UTC

This issue did NOT affect the version of the subversion package,
as shipped with Red Hat Enterprise Linux 4, as it did not include
the lock working copy paths feature.

This issue affects the versions of the subversion package, as shipped
with Red Hat Enterprise Linux 5 and 6.

--

This issue affects the versions of the subversion package, as shipped
with Fedora release of 13 and 14.
