Background ========== GIMPS is a client for the distributed Great Internet Mersenne Prime Search. SETI@home is the client for the Search for Extraterrestrial Intelligence (SETI) project. ChessBrain is the client for the distributed chess supercomputer. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-sci/gimps <= 23.9 >= 23.9-r1 2 app-sci/setiathome <= 3.08-r3 >= 3.08-r4 *>= 3.03-r2 3 app-sci/chessbrain <= 20407 >= 20407-r1 ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== GIMPS, SETI@home and ChessBrain ebuilds install user-owned binaries and init scripts which are executed with root privileges. Impact ====== This could lead to a local privilege escalation or root compromise. Workaround ========== There is no known workaround at this time. Resolution ========== All GIMPS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-sci/gimps-23.9-r1" All SETI@home users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-sci/setiathome-3.08-r4" All ChessBrain users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-sci/chessbrain-20407-r1" Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-26.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.
