Background ========== Xpdf is a PDF file viewer that runs under the X Window System. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf < 3.02-r2 >= 3.02-r2 Description =========== Erik Wallin reported that Gentoo's Xpdf attempts to read the "xpdfrc" file from the current working directory if it cannot find a ".xpdfrc" file in the user's home directory. This is caused by a missing definition of the SYSTEM_XPDFRC macro when compiling a repackaged version of Xpdf. Impact ====== A local attacker could entice a user to run "xpdf" from a directory containing a specially crafted "xpdfrc" file, resulting in the execution of arbitrary code when attempting to, e.g., print a file. Workaround ========== Do not run Xpdf from untrusted working directories. Resolution ========== All Xpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/xpdf-3.02-r2" References ========== [ 1 ] CVE-2009-1144 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1144 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200904-07.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.
