Details

Matt Lewis discovered that Subversion did not properly sanitize its input
when processing svndiff streams, leading to various integer and heap
overflows. If a user or automated system processed crafted input, a remote
attacker could cause a denial of service or potentially execute arbitrary
code as the user processing the input.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.04
Ubuntu 8.10
Ubuntu 8.04

After a standard system upgrade you need to restart any applications that
use Subversion, such as Apache when using mod_dav_svn, to effect the
necessary changes.
