In addition, specific timing behavior must be met for the affected code to be in a state where it can be exploited, making the exploitation of this flaw under normal conditions fairly difficult. In detail, the targeted socket on the remote end must be closed/terminated, which may trigger the error (use-after-free), which then allows for the exploitation to happen. *** Bug 1489092 has been marked as a duplicate of this bug. *** |
