Medium: subversion, mod_dav_svn

Issue Overview:

It was discovered that Subversion’s mod_dontdothat module and Subversion clients using http(s):// are vulnerable to a denial-of-service attack caused by exponential XML entity expansion. An authenticated remote attacker can cause denial-of-service conditions on the server using mod_dontdothat by sending a specially crafted REPORT request. The attack does not require access to a particular repository.

Affected Packages:

subversion, mod_dav_svn
