Mozilla Thunderbird is a standalone mail and newsgroup client. Several flaws were found in the processing of malformed HTML mail content. An HTML mail message containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-2462, CVE-2009-2463, CVE-2009-2466, CVE-2009-3072, CVE-2009-3075, CVE-2009-3380, CVE-2009-3979, CVE-2010-0159) A use-after-free flaw was found in Thunderbird. An attacker could use this flaw to crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-3077) A heap-based buffer overflow flaw was found in the Thunderbird string to floating point conversion routines. An HTML mail message containing malicious JavaScript could crash Thunderbird or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-0689) A use-after-free flaw was found in Thunderbird. Under low memory conditions, viewing an HTML mail message containing malicious content could result in Thunderbird executing arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-1571) A flaw was found in the way Thunderbird created temporary file names for downloaded files. If a local attacker knows the name of a file Thunderbird is going to download, they can replace the contents of that file with arbitrary contents. (CVE-2009-3274) A flaw was found in the way Thunderbird displayed a right-to-left override character when downloading a file. In these cases, the name displayed in the title bar differed from the name displayed in the dialog body. An attacker could use this flaw to trick a user into downloading a file that has a file name or extension that is different from what the user expected. (CVE-2009-3376) A flaw was found in the way Thunderbird processed SOCKS5 proxy replies. A malicious SOCKS5 server could send a specially-crafted reply that would cause Thunderbird to crash. (CVE-2009-2470) Descriptions in the dialogs when adding and removing PKCS #11 modules were not informative. An attacker able to trick a user into installing a malicious PKCS #11 module could use this flaw to install their own Certificate Authority certificates on a user's machine, making it possible to trick the user into believing they are viewing trusted content or, potentially, execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2009-3076) All Thunderbird users should upgrade to this updated package, which resolves these issues. All running instances of Thunderbird must be restarted for the update to take effect.
