Synopsis: Critical: thunderbird security update Issue Date: 2012-10-09 CVE Numbers: CVE-2012-1956 CVE-2012-3982 CVE-2012-3986 CVE-2012-3988 CVE-2012-3991 CVE-2012-3994 CVE-2012-3993 CVE-2012-4184 CVE-2012-3992 CVE-2012-3995 CVE-2012-4179 CVE-2012-4180 CVE-2012-4181 CVE-2012-4182 CVE-2012-4183 CVE-2012-4185 CVE-2012-4186 CVE-2012-4187 CVE-2012-4188 CVE-2012-3990 -- 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-2012-3982, CVE-2012-3988, CVE-2012-3990, CVE-2012-3995, CVE-2012-4179, CVE-2012-4180, CVE-2012-4181, CVE-2012-4182, CVE-2012-4183, CVE-2012-4185, CVE-2012-4186, CVE-2012-4187, CVE-2012-4188) Two flaws in Thunderbird could allow malicious content to bypass intended restrictions, possibly leading to information disclosure, or Thunderbird executing arbitrary code. Note that the information disclosure issue could possibly be combined with other flaws to achieve arbitrary code execution. (CVE-2012-3986, CVE-2012-3991) Multiple flaws were found in the location object implementation in Thunderbird. Malicious content could be used to perform cross-site scripting attacks, script injection, or spoofing attacks. (CVE-2012-1956, CVE-2012-3992, CVE-2012-3994) Two flaws were found in the way Chrome Object Wrappers were implemented. Malicious content could be used to perform cross-site scripting attacks or cause Thunderbird to execute arbitrary code. (CVE-2012-3993, CVE-2012-4184) 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. After installing the update, Thunderbird must be restarted for the changes to take effect. -- SL5 x86_64 thunderbird-10.0.8-1.el5_8.x86_64.rpm i386 thunderbird-10.0.8-1.el5_8.i386.rpm SL6 x86_64 thunderbird-10.0.8-1.el6_3.x86_64.rpm i386 thunderbird-10.0.8-1.el6_3.i686.rpm - Scientific Linux Development Team
