Details
USN-3388-1 fixed several vulnerabilities in Subversion. This update
provides the corresponding update for Ubuntu 12.04 ESM.
Ivan Zhakov discovered that Subversion did not properly handle
some requests. A remote attacker could use this to cause a
denial of service. (CVE-2016-2168)
Original advisory 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. (CVE-2016-2167)
