FreeBSD : subversion -- Arbitrary code execution vulnerability (6e80bd9b-7e9b-11e7-abfe-90e2baa3bafc)

high Nessus Plugin ID 102466

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

subversion team reports :

A Subversion client sometimes connects to URLs provided by the repository. This happens in two primary cases: during 'checkout', 'export', 'update', and 'switch', when the tree being downloaded contains svn:externals properties; and when using 'svnsync sync' with one URL argument.

A maliciously constructed svn+ssh:// URL would cause Subversion clients 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://.

An exploit has been tested.

Solution

Update the affected packages.
