This signature detects attempts to exploit a known vulnerability against Mozilla Firefox. It is due to a specific method call on an object with an unassigned mChannel, resulting in a dangling pointer. A remote attacker could exploit this vulnerability by enticing a user to visit a malicious web page. A successful attack would result in execution of arbitrary code in the security context of the browser's user.
Mozilla Firefox and SeaMonkey are prone to a memory-corruption vulnerability that may allow remote code execution. An attacker can exploit this issue by enticing an unsuspecting user into viewing malicious content. A successful exploit will result in the execution of arbitrary attacker-supplied code in the context of the user running the affected application. Failed exploit attempts will likely result in denial-of-service conditions. This issue is fixed in: Firefox 3.6.17 Firefox 3.5.19 SeaMonkey 2.0.14 NOTE: This issue was previously discussed in BID 47635 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2011-12 through -18 Multiple Vulnerabilities) but has been moved to its own record to better document it.
