An updated thunderbird package that fixes multiple security issues is now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security has rated this update as having Important 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.

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2015-4473, CVE-2015-4491, CVE-2015-4487, CVE-2015-4488, CVE-2015-4489)

Note: All of the above issues cannot be exploited by a specially crafted HTML mail message because JavaScript is disabled by default for mail messages. However, they could be exploited in other ways in Thunderbird (for example, by viewing the full remote content of an RSS feed).

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Gary Kwong, Christian Holler, Byron Campen, Gustavo Grieco, and Ronald Crane as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 38.2. You can find a link to the Mozilla advisories in the References section of this erratum.

All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 38.2, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.

Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser: Multiple memory safety errors, integer overflows, buffer overflows, use-after-frees and other implementation errors may lead to the execution of arbitrary code, bypass of the same-origin policy or denial of service.

Debian follows the extended support releases (ESR) of Firefox. Support for the 31.x series has ended, so starting with this update we're now following the 38.x releases.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2712-1 advisory.

    Gary Kwong, Christian Holler, and Byron Campen discovered multiple memory safety issues in Thunderbird. If     a user were tricked in to opening a specially crafted message, an attacker could potentially exploit these     to cause a denial of service via application crash, or execute arbitrary code with the privileges ofthe     user invoking Thunderbird. (CVE-2015-4473)

    Ronald Crane reported 3 security issues. If a user were tricked in to opening a specially crafted message,     an attacker could potentially exploit these, in combination with another security vulnerability, to cause     a denial of service via application crash, or execute arbitrary code with the privileges of the user     invoking Thunderbird. (CVE-2015-4487, CVE-2015-4488, CVE-2015-4489)

    Gustavo Grieco discovered a heap overflow in gdk-pixbuf. If a user were tricked in to opening a specially     crafted message, an attacker could potentially exploit this to cause a denial of service via application     crash or execute arbitrary code with the priviliges of the user invoking Thunderbird. (CVE-2015-4491)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Mozilla NSS switched the CKBI ABI from 1.98 to 2.4, which is what Firefox 38ESR uses.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
