Insight

Insight

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 ma ...
