Matthew Palmer discovered an underflow flaw in apr-util. An attacker
could cause a denial of service via application crash in Apache using
a crafted SVNMasterURI directive, .htaccess file, or when using

It was discovered that the XML parser did not properly handle entity

Ubuntu are not considered to be at risk. (CVE-2009-1956).
