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-2012-1948,
CVE-2012-1951, CVE-2012-1952, CVE-2012-1953, CVE-2012-1954, CVE-2012-1958,
CVE-2012-1962, CVE-2012-1967)
Malicious content could bypass same-compartment security wrappers (SCSW)
and execute arbitrary code with chrome privileges. (CVE-2012-1959)
A flaw in the way Thunderbird called history.forward and history.back could
allow an attacker to conceal a malicious URL, possibly tricking a user
into believing they are viewing trusted content. (CVE-2012-1955)
A flaw in a parser utility class used by Thunderbird to parse feeds (such
as RSS) could allow an attacker to execute arbitrary JavaScript with the
privileges of the user running Thunderbird. This issue could have affected
other Thunderbird components or add-ons that assume the class returns
sanitized input. (CVE-2012-1957)
A flaw in the way Thunderbird handled X-Frame-Options headers could allow
malicious content to perform a clickjacking attack. (CVE-2012-1961)
A flaw in the way Content Security Policy (CSP) reports were generated by
Thunderbird could allow malicious content to steal a victim's OAuth 2.0
access tokens and OpenID credentials. (CVE-2012-1963)
A flaw in the way Thunderbird handled certificate warnings could allow a
man-in-the-middle attacker to create a crafted warning, possibly tricking
a user into accepting an arbitrary certificate as trusted. (CVE-2012-1964)
The nss update RHBA-2012:0337 for Red Hat Enterprise Linux 5 and 6
introduced a mitigation for the CVE-2011-3389 flaw. For compatibility
reasons, it remains disabled by default in the nss packages. This update
makes Thunderbird enable the mitigation by default. It can be disabled by
setting the NSS_SSL_CBC_RANDOM_IV environment variable to 0 before
launching Thunderbird. (BZ#838879)
Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Benoit Jacob, Jesse Ruderman, Christian Holler, Bill
McCloskey, Abhishek Arya, Arthur Gerkis, Bill Keese, moz_bug_r_a4, Bobby
Holley, Mariusz Mlynski, Mario Heiderich, Frédéric Buclin, Karthikeyan
Bhargavan, and Matt McCutchen as the original reporters of these issues.
Note: None of the issues in this advisory can 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 10.0.6 ESR, which corrects these issues. After
installing the update, Thunderbird must be restarted for the changes to
take effect.
