Subject:		OpenServer 5.0.6 OpenServer 5.0.7 : apache mod_digest Incorrect Client Response Verification Vulnerability
Advisory number: 	SCOSA-2004.14
Issue date: 		2004 August 31
Cross reference:	sr889564 fz528952 erg712565 CAN-2003-0987

1. Problem Description

	Dirk-Willem van Gulik has reported a vulnerability in Apache
	mod_digest. mod_digest does not properly verify the nonce
	of a client response. A remote user may be able to replay
	a response to be authenticated in certain cases. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2003-0987 to this issue.
