Severity: Normal Title: xli, xloadimage: Multiple vulnerabilities Date: March 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 ------------------------------------------------------------------- 1 media-gfx/xloadimage < 4.1-r2 >= 4.1-r2 2 media-gfx/xli < 1.17.0-r1 >= 1.17.0-r1 ------------------------------------------------------------------- 2 affected packages on all of their 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"
