CVE-2016-2167
Published: 05 May 2016
The canonicalize_username function in svnserve/cyrus_auth.c in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4, when Cyrus SASL authentication is used, allows remote attackers to authenticate and bypass intended access restrictions via a realm string that is a prefix of an expected repository realm string.
From the Ubuntu security team
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.
