SUSE-SA:2006:062: openssh

High Nessus Plugin ID 24440


The remote host is missing a vendor-supplied security patch


The remote host is missing the patch for the advisory SUSE-SA:2006:062 (openssh).

Several security problems were fixed in OpenSSH 4.4 and the bug fixes were back ported to the openssh versions in our products.

- CVE-2006-4924: A denial of service problem has been fixed in OpenSSH which could be used to cause lots of CPU consumption on a remote openssh server.

- CVE-2006-4925: If a remote attacker is able to inject network traffic this could be used to cause a client connection to close.

- CVE-2006-5051: Fixed an unsafe signal handler reported by Mark Dowd. The signal handler was vulnerable to a race condition that could be exploited to perform a pre-authentication denial of service. This vulnerability could theoretically lead to pre-authentication remote code execution if GSSAPI authentication is enabled, but the likelihood of successful exploitation appears remote.

- CVE-2006-5052: Fixed a GSSAPI authentication abort that could be used to determine the validity of user names on some platforms.
