I believe this vulnerability has been mislablled as a denial of service
vulnerability, rather than an information disclosure vulnerability:
According to various sources, eg
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5794
https://bugzilla.redhat.com/show_bug.cgi?id=154314
This bug may allow users to obtain effective credentials of a different
user (under certain confurations).
It may be worth reissuing the advisory to make this clear.
Dominic.
