Mozilla released patches for 15 security advisories (the most in nearly two years), for Firefox, Thunderbird, and SeaMonkey. Five bugs are rated critical, four high, and six moderate.

Security researchers found a vulnerability that could enable a remote attacker to short-circuit a page load in Firefox via the drag-and-drop mechanism. Normally, when you drag and drop a URL into the address bar, that URL loads automatically. But the short-circuit, which is triggered by dragging and dropping a malicious address, lets hackers spoof the address bar and opens your system to phishing attacks.

Mozilla also identified and fixed several memory corruption bugsrated highin the browser engine used in Mozilla-based products that could potentially be exploited to run arbitrary code on your system. Another memory corruption bug could cause your program to crash.

These vulnerabilities and others are corrected in Firefox 13, 14, and ESR 10.0.6; Thunderbird 13, 14, and ESR 10.0.6; and SeaMonkey 2.11.
