CentOS 5 / 6 : thunderbird (CESA-2013:0982)
Critical Nessus Plugin ID 66997
SynopsisThe remote CentOS host is missing a security update.
DescriptionAn updated thunderbird package that fixes several security issues is now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team 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 content.
Malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2013-1682, CVE-2013-1684, CVE-2013-1685, CVE-2013-1686, CVE-2013-1687, CVE-2013-1690)
It was found that Thunderbird allowed data to be sent in the body of XMLHttpRequest (XHR) HEAD requests. In some cases this could allow attackers to conduct Cross-Site Request Forgery (CSRF) attacks.
Timing differences in the way Thunderbird processed SVG image files could allow an attacker to read data across domains, potentially leading to information disclosure. (CVE-2013-1693)
Two flaws were found in the way Thunderbird implemented some of its internal structures (called wrappers). An attacker could use these flaws to bypass some restrictions placed on them. This could lead to unexpected behavior or a potentially exploitable crash.
Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Gary Kwong, Jesse Ruderman, Andrew McCreight, Abhishek Arya, Mariusz Mlynski, Nils, Johnathan Kuskos, Paul Stone, Boris Zbarsky, and moz_bug_r_a4 as the original reporters of these issues.
All Thunderbird users should upgrade to this updated package, which contains Thunderbird version 17.0.7 ESR, which corrects these issues.
After installing the update, Thunderbird must be restarted for the changes to take effect.
SolutionUpdate the affected thunderbird package.
