Vulnerability CVE-2007-4752


Published: 2007-09-11   Modified: 2012-02-12

Description:
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.
