SuSE 10 Security Update : OpenSSH (ZYPP Patch Number 4580)

High Nessus Plugin ID 29540


The remote SuSE 10 host is missing a security-related patch.


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.


Apply ZYPP patch number 4580.
