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 < 0.7.5.2 >= 0.7.5.2 Description =========== Multiple vulnerabilities have been discovered in Ettercap: * Ettercap does not handle temporary files securely (CVE-2010-3843). * A format string flaw in Ettercap could cause a buffer overflow (CVE-2010-3844). * A stack-based buffer overflow exists in Ettercap (CVE-2013-0722). Impact ====== A remote attacker could entice a user to load a specially crafted configuration file using Ettercap, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition. A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All Ettercap users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.5.2" References ========== [ 1 ] CVE-2010-3843 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3843 [ 2 ] CVE-2010-3844 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3844 [ 3 ] CVE-2013-0722 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0722 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201405-12.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.
