SuSE9 Security Update : OpenSSH (YOU Patch Number 11931)
High Nessus Plugin ID 41158
SynopsisThe remote SuSE 9 host is missing a security-related patch.
Description- This update fixes a bug in ssh's cookie handling code.
It does not properly handle the situation when an untrusted cookie cannot be created and uses a trusted X11 cookie instead. This allows attackers to violate the intended policy and gain privileges by causing an X client to be treated as trusted. (CVE-2007-4752)
- Additionally this update fixes a bug introduced with the last security update for openssh. When the SSH daemon wrote to stderr (for instance, to warn about the presence of a deprecated option like PAMAuthenticationViaKbdInt in its configuration file), SIGALRM was blocked for SSH sessions. This resulted in problems with processes which rely on SIGALRM, such as ntpdate.
