IAVA: 2008-T-0046

Details

The MITRE CVE dictionary describes this issue as:

ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted.
