Several security problems were fixed in OpenSSH :

  • 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-2006-4924)

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

  • Fixed an unsafe signal hander 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-2006-5051)

  • Fixed a GSSAPI authentication abort that could be used to determine the validity of usernames on some platforms. (CVE-2006-5052)
