Background ========== Ethereal is a feature rich network protocol analyzer. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/ethereal < 0.10.10 >= 0.10.10 Description =========== There are multiple vulnerabilities in versions of Ethereal earlier than 0.10.10, including: * The Etheric and 3GPP2 A11 dissectors are vulnerable to buffer overflows (CAN-2005-0704 and CAN-2005-0699). * The GPRS-LLC could crash when the "ignore cipher bit" option is enabled (CAN-2005-0705). * Various vulnerabilities in the IAPP, JXTA, and sFlow dissectors. Impact ====== An attacker might be able to use these vulnerabilities to crash Ethereal and execute arbitrary code with the permissions of the user running Ethereal, which could be the root user. Workaround ========== For a temporary workaround you can disable all affected protocol dissectors. However, it is strongly recommended that you upgrade to the latest stable version. Resolution ========== All Ethereal users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.10" References ========== [ 1 ] CAN-2005-0699 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0699 [ 2 ] CAN-2005-0704 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0704 [ 3 ] CAN-2005-0705 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0705 [ 4 ] Ethereal enpa-sa-00018 http://www.ethereal.com/appnotes/enpa-sa-00018.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200503-16.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.
