Background ========== Ettercap is a suite of tools for content filtering, sniffing and man in the middle attacks on a LAN. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/ettercap < 0.7.3 >= 0.7.3 Description =========== The curses_msg function of Ettercap's Ncurses-based user interface insecurely implements formatted printing. Impact ====== A remote attacker could craft a malicious network flow that would result in executing arbitrary code with the rights of the user running the Ettercap tool, which is often root. Workaround ========== There is no known workaround at this time. Resolution ========== All Ettercap users should upgrade to the latest available version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.3" References ========== [ 1 ] CAN-2005-1796 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1796 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200506-07.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.
