Subject:		OpenLinux: mpg123 remote denial of service and heap-based buffer overflow
Advisory number: 	CSSA-2004-002.0
Issue date: 		2004 February 19
Cross reference: 	sr882700 fz528149 erg712383 CAN-2003-0577 CAN-2003-0865
______________________________________________________________________________


1. Problem Description

	mpg123 0.59r allows remote attackers to cause a denial of
	service and possibly execute arbitrary code via an MP3 file
	with a zero bitrate, which creates a negative frame size. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org)
	has assigned the name CAN-2003-0577 to this issue. 

	Heap-based buffer overflow in readstring of httpget.c for mpg123 
	0.59r and 0.59s allows remote attackers to execute arbitrary code 
	via a long request. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2003-0865 to this issue.


2. Vulnerable Supported Versions

	System				Package
	----------------------------------------------------------------------
	OpenLinux 3.1.1 Server		prior to mpg123-0.59r-7MR.i386.rpm
	OpenLinux 3.1.1 Workstation	prior to mpg123-0.59r-7MR.i386.rpm


3. Solution

	The proper solution is to install the latest packages. Many
	customers find it easier to use the Caldera System Updater, called
	cupdate (or kcupdate under the KDE environment), to update these
	packages rather than downloading and installing them by hand.
