"From Red Hat Security Advisory 2017:2480 :

An update for subversion is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Subversion (SVN) is a concurrent version control system which enables
one or more users to collaborate in developing and maintaining a
hierarchy of files and directories while keeping a history of all
changes.

Security Fix(es) :

* A shell command injection flaw related to the handling of 'svn+ssh'
URLs has been discovered in Subversion. An attacker could use this
flaw to execute shell commands with the privileges of the user running
the Subversion client, for example when performing a 'checkout' or
'update' action on a malicious repository, or a legitimate repository
containing a malicious commit. (CVE-2017-9800)

Red Hat would like to thank the Subversion Team for reporting this
issue."
