Description

LSAC(v2)
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-2013-1701) A flaw was found in the way Thunderbird generated Certificate Request Message Format (CRMF) requests. An attacker could use this flaw to perform cross-site scripting (XSS) attacks or execute arbitrary code with the privileges of the user running Thunderbird. (CVE-2013-1710) A flaw was found in the way Thunderbird handled the interaction between frames and browser history. An attacker could use this flaw to trick Thunderbird into treating malicious content as if it came from the browser history, allowing for XSS attacks. (CVE-2013-1709) It was found that the same-origin policy could be bypassed due to the way Uniform Resource Identifiers (URI) were checked in JavaScript. An attacker could use this flaw to perform XSS attacks, or install malicious add-ons from third-party pages. (CVE-2013-1713) It was found that web workers could bypass the same-origin policy. An attacker could use this flaw to perform XSS attacks. (CVE-2013-1714) It was found that, in certain circumstances, Thunderbird incorrectly handled Java applets. If a user launched an untrusted Java applet via Thunderbird, the applet could use this flaw to obtain read-only access to files on the user's local system. (CVE-2013-1717) Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Jeff Gilbert, Henrik Skupin, moz_bug_r_a4, Cody Crews, Federico Lanusse, and Georgi Guninski 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 17.0.8 ESR, which corrects these issues. After installing the update, Thunderbird must be restarted for the changes to take effect.
