Background ========== Mozilla Thunderbird is a popular open-source email client from the Mozilla Project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mozilla-thunderbird < 1.5.0.9 >= 1.5.0.9 2 mozilla-thunderbird-bin < 1.5.0.9 >= 1.5.0.9 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Georgi Guninski and David Bienvenu discovered buffer overflows in the processing of long "Content-Type:" and long non-ASCII MIME headers. Additionally, Frederik Reiss discovered a heap-based buffer overflow in the conversion of a CSS cursor. Different vulnerabilities involving memory corruption in the browser engine were also fixed. Mozilla Thunderbird also contains less severe vulnerabilities involving JavaScript and Java. Impact ====== An attacker could entice a user to view a specially crafted email that will trigger one of these vulnerabilities, possibly leading to the execution of arbitrary code. An attacker could also perform cross-site scripting attacks, leading to the exposure of sensitive information, like user credentials. Note that the execution of JavaScript or Java applets is disabled by default and enabling it is strongly discouraged. Workaround ========== There are no known workarounds for all the issues at this time. Resolution ========== All Mozilla Thunderbird users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.5.0.9" All Mozilla Thunderbird binary release users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.5.0.9" References ========== [ 1 ] CVE-2006-6497 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6497 [ 2 ] CVE-2006-6500 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6500 [ 3 ] CVE-2006-6501 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6501 [ 4 ] CVE-2006-6502 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6502 [ 5 ] CVE-2006-6503 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6503 [ 6 ] CVE-2006-6505 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6505 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-03.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.
