Description Jan Lieskovsky 2011-01-06 17:53:56 UTC

A server-side memory leak in Subversion before v1.6.15
allowed remote attackers to cause a denial of service
(memory consumption and daemon outage or crash) via
Subversion client "blame" or "log" operations performed 
on certain repository files, when the -g option (request 
to display additional merge history for the file) was used.

Comment 1 Jan Lieskovsky 2011-01-06 18:00:20 UTC

This issue did not affect the versions of the subversion package,
as shipped with Red Hat Enterprise Linux 4 and 5, as they did not
support -g / --use-merge-history options yet.

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

--

This issue affects the version of the subversion package,
as shipped with Fedora release of 13.

The subversion-1.6.15-1.fc14 package for Fedora-14, currently
present in -testing repository already contains fix for this issue.
