Severity:	normal
Title:	xli, xloadimage: Multiple vulnerabilities
Date:	03/02/2005
Bugs:	#79762
ID:	200503-05

Synopsis

xli and xloadimage are vulnerable to multiple issues, potentially leading to the execution of arbitrary code.

Background

xli and xloadimage are X11 utilities for displaying and manipulating a wide range of image formats.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-gfx/xloadimage	< 4.1-r2	>= 4.1-r2	All supported architectures
media-gfx/xli	< 1.17.0-r1	>= 1.17.0-r1	All supported architectures

Description

Tavis Ormandy of the Gentoo Linux Security Audit Team has reported that xli and xloadimage contain a flaw in the handling of compressed images, where shell meta-characters are not adequately escaped. Rob Holland of the Gentoo Linux Security Audit Team has reported that an xloadimage vulnerability in the handling of Faces Project images discovered by zen-parse in 2001 remained unpatched in xli. Additionally, it has been reported that insufficient validation of image properties in xli could potentially result in buffer management errors.

Impact

Successful exploitation would permit a remote attacker to execute arbitrary shell commands, or arbitrary code with the privileges of the xloadimage or xli user.

Workaround

There is no known workaround at this time.

Resolution

All xli users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/xli-1.17.0-r1"

All xloadimage users should also upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/xloadimage-4.1-r2"
