Background ========== GNU ed is a basic line editor. red is a restricted version of ed that does not allow shell command execution. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/ed < 1.0 >= 1.0 Description =========== Alfredo Ortega from Core Security Technologies reported a heap-based buffer overflow in the strip_escapes() function when processing overly long filenames. Impact ====== A remote attacker could entice a user to process specially crafted commands with ed or red, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All GNU ed users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/ed-1.0" References ========== [ 1 ] CVE-2008-3916 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3916 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200809-15.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.
