			SCO Security Advisory

Subject:		UnixWare 7.1.3 UnixWare 7.1.4 : Lynx Command Injection Vulnerability
Advisory number:	SCOSA-2005.55
Issue date:		2005 December 14
Cross reference:	fz533314
			CVE-2005-2929
			
______________________________________________________________________________


1. Problem Description

	Remote exploitation of a command injection vulnerability  could
	allow attackers to execute arbitrary commands with the
	privileges of the underlying user.
	
	The problem specifically exists within the feature to execute
	local cgi-bin programs via the "lynxcgi:" URI handler. The
	handler is generally intended to be restricted to a specific
	directory or program(s). However, due to a configuration error
	on multiple platforms, the default settings allow for arbitrary
	websites to specify commands to run as the user running Lynx.
	
	The Common Vulnerabilities and Exposures project (cve.mitre.org)
	has assigned the name CVE-2005-2929 to this issue.


2. Vulnerable Supported Versions
