Description SMASH SMASH 2023-11-15 08:56:00 UTC

There exists a use after free/double free in libwebp. An attacker can use
the ApplyFiltersAndEncode() function and loop through to free best.bw and assign
best = trial pointer. The second loop will then return 0 because of an Out of
memory error in VP8 encoder, the pointer is still assigned to trial and the
AddressSanitizer will attempt a double free.
