svnserve, the svn:// protocol server, can optionally use the Cyrus SASL library for authentication, integrity protection, and encryption. Due to a programming oversight, authentication against Cyrus SASL would permit the remote user to specify a realm string which is a prefix of the expected realm string.
CVE-2016-2168
Subversion's httpd servers are vulnerable to a remotely triggerable crash in the mod_authz_svn module. The crash can occur during an authorization check for a COPY or MOVE request with a specially crafted header value.
This allows remote attackers to cause a denial of service.
For Debian 7 Wheezy, these issues have been fixed in subversion version 1.6.17dfsg-4+deb7u11");
