Apache Subversion < 1.6.4 'libsvn_delta' Library Binary Delta svndiff Stream Parsing Multiple Overflows

High Nessus Plugin ID 40620


The remote host has an application that is affected by multiple heap overflow issues.


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.


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.
