NVD Description

Note: Versions mentioned in the description apply only to the upstream subversion package and not the subversion package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

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.
