The (1) mod_dav_svn and (2) svnserve servers in Subversion 1.6.0 through 1.7.19 and 1.8.0 through 1.8.11 allow remote attackers to cause a denial of service (assertion failure and abort) via crafted parameter combinations related to dynamically evaluated revision numbers.

A maliciously constructed svn+ssh:// URL would cause Subversion clients before 1.8.19, 1.9.x before 1.9.7, and 1.10.0.x through 1.10.0-alpha3 to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server. The vulnerability affects all clients, including those that use file://, http://, and plain (untunneled) svn://.

In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion's svnserve server process may exit when a well-formed read-only request produces a particular answer. This can lead to disruption for users of the server.

In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion's svnserve server process may exit when a client sends certain sequences of protocol commands. This can lead to disruption for users of the server.

The svn_repos_trace_node_locations function in Apache Subversion before 1.7.21 and 1.8.x before 1.8.14, when path-based authorization is used, allows remote authenticated users to obtain sensitive path information by reading the history of a node that has been moved from a hidden path.
