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."

(Subversion: Arbitrary code execution)

    Specially crafted ‘ssh://...’ URLs may allow the owner of the
      repository to execute arbitrary commands on client’s machine if those
      commands are already installed on the client’s system. This is
      especially dangerous when the third-party repository has one or more
      submodules with specially crafted ‘ssh://...’ URLs. Each time the
      repository is recursively cloned or submodules are updated the payload
      will be triggered.
  
Impact :

    A remote attacker, by enticing a user to clone a specially crafted
      repository, could possibly execute arbitrary code with the privileges of
      the process.
  
Workaround :

    There are several alternative ways to fix this vulnerability. Please

host names in 'svn+ssh://' URLs. A remote attacker could use this to
construct a subversion repository that when accessed could run
arbitrary code with the privileges of the user. (CVE-2017-9800)

Daniel Shahaf and James McCoy discovered that Subversion did not
properly verify realms when using Cyrus SASL authentication. A remote
attacker could use this to possibly bypass intended access
restrictions. This issue only affected Ubuntu 14.04 LTS and Ubuntu
16.04 LTS. (CVE-2016-2167)

Florian Weimer discovered that Subversion clients did not properly
restrict XML entity expansion when accessing http(s):// URLs. A remote
attacker could use this to cause a denial of service. This issue only
affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-8734).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
