Description
Security researcher regenrecht reported via
TippingPoint's Zero Day Initiative that a method used
by JSON.stringify contained a use-after-free error in
which a currently in-use pointer was freed and subsequently
dereferenced. This could lead to arbitrary code execution if an
attacker was able to store malicious code in the freed section of
memory.
Mozilla developer Igor Bukanov also independently discovered and reported this issue two weeks after the initial report was received.
