The installed version of Subversion Client or Server is affected by multiple heap overflow issues.Specifically, the 'libsvn_delta' library fails to perform sufficient boundary checks before processing certain svndiff streams. An attacker with commit access to a vulnerable Subversion server can exploit this vulnerability from a Subversion client to trigger a heap overflow on the server. Typically such an attack would result in a denial of service condition or arbitrary code execution on the remote server.
An attacker can also trigger this issue from a rogue Subversion server on a Subversion client in response to a checkout or update request.
Solution
Upgrade to Subversion Client/Server 1.6.4 or later.If using Subversion Client/Server 1.5.x, make sure you are using version CollabNet binaries 1.5.7 or later.
