  "description": "Mozilla Firefox is a standalone web browser, designed for standards compliance and performance.  Its functionality can be enhanced via a plethora of extensions.\r\n\r\nSecurity Fix(es):\r\n\r\nThere 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. \n(CVE-2023-1999)",
