3. Description:

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.
(CVE-2013-1692)

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. (CVE-2013-1694, CVE-2013-1697)

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.

Note: All of the above issues cannot be exploited by a specially-crafted
HTML mail message as JavaScript is disabled by default for mail messages.
They could be exploited another way in Thunderbird, for example, when
viewing the full remote content of an RSS feed.

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.
