Description
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.
The Mozilla Foundation Security Advisory describes this flaw as:
A double-free in libwebp could have led to memory corruption and a potentially exploitable crash.
