Description Jan Lieskovsky 2013-06-03 11:14:57 UTC

A denial of service flaw was found in the way svnserve tool of Subversion, a concurrent version control system, managed remote client TCP connections that got closed early in the connection process (previously aborted connections were treated as critical errors, resulting into svnserve termination). A remote attacker could use this flaw to cause denial of service (svnserve daemon exit, leading to disruption of SVN service to other users).
