Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes

Description:   A vulnerability was reported in Mozilla Firefox. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create specially crafted content that triggers a resize event where the referenced '<canvas>' element undergoes a style change that deletes the original canvas reference. When the content is loaded by the target user, a use-after-free memory error will occur in nsIPresShell and arbitrary code will be executed on the target user's system.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.
