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" References ========== [ 1 ] CAN-2001-0775 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2001-0775 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-05.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
