"A potential remote exploit was found in the bdecode_recursive routine
that could trigger a stack overflow when passed malformed message
data. This release adds a fix for this issue from the upstream
subversion repository that limits the maximum recursive depth of this
function.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
