Background ========== Mozilla Thunderbird is a popular open-source email client from the Mozilla Project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mozilla-thunderbird < 1.5.0.8 >= 1.5.0.8 2 mozilla-thunderbird-bin < 1.5.0.8 >= 1.5.0.8 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== It has been identified that Mozilla Thunderbird improperly handles Script objects while they are being executed, allowing them to be modified during execution. JavaScript is disabled in Mozilla Thunderbird by default. Mozilla Thunderbird has also been found to be vulnerable to various potential buffer overflows. Lastly, the binary release of Mozilla Thunderbird is vulnerable to a low exponent RSA signature forgery issue because it is bundled with a vulnerable version of NSS. Impact ====== An attacker could entice a user to view a specially crafted email that causes a buffer overflow and again executes arbitrary code or causes a Denial of Service. An attacker could also entice a user to view an email containing specially crafted JavaScript and execute arbitrary code with the rights of the user running Mozilla Thunderbird. It is important to note that JavaScript is off by default in Mozilla Thunderbird, and enabling it is strongly discouraged. It is also possible for an attacker to create SSL/TLS or email certificates that would not be detected as invalid by the binary release of Mozilla Thunderbird, raising the possibility for Man-in-the-Middle attacks. Workaround ========== There is no known workaround at this time. Resolution ========== Users upgrading to the following releases of Mozilla Thunderbird should note that this version of Mozilla Thunderbird has been found to not display certain messages in some cases. </br> </br> All Mozilla Thunderbird users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-1.5.0.8" All Mozilla Thunderbird binary release users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-1.5.0.8" References ========== [ 1 ] CVE-2006-5462 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5462 [ 2 ] CVE-2006-5463 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5463 [ 3 ] CVE-2006-5464 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5464 [ 4 ] CVE-2006-5747 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5747 [ 5 ] CVE-2006-5748 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-5748 [ 6 ] Mozilla Thunderbird Email Loss Bug https://bugzilla.mozilla.org/show_bug.cgi?id=360409 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200612-06.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.
