-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Critical: thunderbird security update Advisory ID: RHSA-2011:0887-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0887.html Issue date: 2011-06-21 CVE Names: CVE-2011-0083 CVE-2011-0085 CVE-2011-2362 CVE-2011-2363 CVE-2011-2364 CVE-2011-2365 CVE-2011-2371 CVE-2011-2373 CVE-2011-2374 CVE-2011-2375 CVE-2011-2376 CVE-2011-2377 ===================================================================== 1. Summary: An updated thunderbird package that fixes several security issues is now available for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Description: Mozilla Thunderbird is a standalone mail and newsgroup client. A flaw was found in the way Thunderbird handled malformed JPEG images. An HTML mail message containing a malicious JPEG image could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2011-2377) Multiple dangling pointer flaws were found in Thunderbird. Malicious HTML content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2011-0083, CVE-2011-0085, CVE-2011-2363) Several flaws were found in the processing of malformed HTML content. Malicious HTML content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375, CVE-2011-2376) An integer overflow flaw was found in the way Thunderbird handled JavaScript Array objects. Malicious content could cause Thunderbird to execute JavaScript with the privileges of the user running Thunderbird. (CVE-2011-2371) A use-after-free flaw was found in the way Thunderbird handled malformed JavaScript. Malicious content could cause Thunderbird to execute JavaScript with the privileges of the user running Thunderbird. (CVE-2011-2373) It was found that Thunderbird could treat two separate cookies (for web content) as interchangeable if both were for the same domain name but one of those domain names had a trailing "." character. This violates the same-origin policy and could possibly lead to data being leaked to the wrong domain. (CVE-2011-2362) All Thunderbird users should upgrade to this updated package, which resolves these issues. All running instances of Thunderbird must be restarted for the update to take effect. 4.
