RHEL 6 / 7 : thunderbird (RHSA-2016:0258)

critical Nessus Plugin ID 88859

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for thunderbird.

Description

The remote Redhat Enterprise Linux 6 / 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2016:0258 advisory.

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-2016-1930, CVE-2016-1935)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Bob Clary, Christian Holler, Nils Ohlmeier, Gary Kwong, Jesse Ruderman, Carsten Book, Randell Jesup, and Aki Helin as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Thunderbird 38.6.0. 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 38.6.0, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL thunderbird package based on the guidance in RHSA-2016:0258.
