Subversion project reports:
svnserve, the svn:// protocol server, can optionally use the Cyrus
SASL library for authentication, integrity protection, and encryption.
Due to a programming oversight, authentication against Cyrus SASL
would permit the remote user to specify a realm string which is
a prefix of the expected realm string.
Subversion's httpd servers are vulnerable to a remotely triggerable crash
in the mod_authz_svn module. The crash can occur during an authorization
check for a COPY or MOVE request with a specially crafted header value.
This allows remote attackers to cause a denial of service.
