CVE-2017-5426
On Linux, if the secure computing mode BPF seccomp-bpf filter is running when the Gecko Media Plugin sandbox is started, the sandbox fails to be applied and items that would run within the sandbox are run protected only by the running filter which is typically weak compared to the sandbox. Note:...
