Background ========== Blam is an RSS and Atom feed reader for GNOME written in C#. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-news/blam < 1.8.4 >= 1.8.4 Description =========== The "/usr/bin/blam" script sets the "LD_LIBRARY_PATH" environment variable incorrectly, which might result in the current working directory (.) being included when searching for dynamically linked libraries of the Mono Runtime application. Impact ====== A local attacker could entice a user to run Blam in a directory containing a specially crafted library file which could result in the execution of arbitrary code with the privileges of the user running Blam. Workaround ========== Do not run Blam from an untrusted working directory. Resolution ========== All Blam users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-news/blam-1.8.4" References ========== [ 1 ] CVE-2005-4790 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-4790 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200801-14.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.
