Severity:	normal
Title:	xzgv: Multiple overflows
Date:	01/06/2005
Bugs:	#74069
ID:	200501-09

Synopsis

xzgv contains multiple overflows that may lead to the execution of arbitrary code.

Background

xzgv is a picture viewer for X, with a thumbnail-based file selector.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/xzgv	<= 0.8	>= 0.8-r1	All supported architectures

Description

Multiple overflows have been found in the image processing code of xzgv, including an integer overflow in the PRF parsing code (CAN-2004-0994).

Impact

An attacker could entice a user to open or browse a specially-crafted image file, potentially resulting in the execution of arbitrary code with the rights of the user running xzgv.

Workaround

There is no known workaround at this time.

Resolution

All xzgv users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/xzgv-0.8-r1"
