Description Jan Lieskovsky 2011-06-07 14:38:56 UTC
It was found that cURL performed client credentials delegation during the
client-to-server GSS security mechanisms negotiation. A remote, rogue
server could use this flaw to impersonate the cURL client (victim) against
the correct (originally intended) server, potentially leading to denial
of cURL tool services for victim client.
