Several security issues were fixed in Subversion.
Software description

– Advanced version control system
Details
Joern Schneeweisz discovered that Subversion did not properly handle
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)
