Subject:		UnixWare 7.1.3 UnixWare 7.1.4 : OpenSSH Multiple Vulnerabilities
Advisory number:	SCOSA-2005.53
Issue date:		2005 December 12
Cross reference:	erg712933 fz532978 sr894960
 			CVE-2005-2797 CVE-2005-2798
______________________________________________________________________________


1. Problem Description

 	Two security issues have been reported in OpenSSH, which can be
 	exploited by malicious users to gain escalated privileges or
 	bypass certain security restrictions.

 	An error in handling dynamic port forwardings when no listen
 	address is specified, can cause "GatewayPorts" to be incorrectly
 	activated.

 	The Common Vulnerabilities and Exposures project (cve.mitre.org)
 	has assigned the name CVE-2005-2797 to this issue.

 	An error in handling GSSAPI credential delegation can allow a
 	user, who did not login using GSSAPI authentication, to be
 	delegated with GSSAPI credentials.

 	Successful exploitation requires that
 	"GSSAPIDelegateCredentials" is enabled.

 	The Common Vulnerabilities and Exposures project (cve.mitre.org)
 	has assigned the name CVE-2005-2798 to this issue.
