        XV Image Viewer - Multiple Buffer Overflow Vulnerabilities
                              26 August 2004

===========================================================================

        AusCERT Alert Summary
        ---------------------

Product:                XV versions 3.10a and prior
Operating System:       UNIX variants
                        Linux variants
Impact:                 Execute Arbitrary Code/Commands
Access:                 Remote/Unauthenticated

- --------------------------BEGIN INCLUDED TEXT--------------------

PROBLEM:  

	XV is an image viewer and image manipulation program for UNIX-like
	operating systems.

	Multiple stack and heap buffer overflows have been identified in XV 
	that allow a remote attacker to execute arbitrary code as the user 
	running XV.


VERSIONS:

	XV versions 3.10a and prior are vulnerable.


IMPACT:   

	This vulnerability can be used by a remote attacker to execute
	arbitrary code as the user running XV. Using XV to view a specially 
	crafted image file can trigger the vulnerability.
	
	AusCERT advises that working exploits for this vulnerability are
	publicly available.


MITIGATION: 
	
	No patch is currently available to fix this vulnerability.
	AusCERT recommends that administrators use a different application to
	replace XV until a patch is available.
