Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 102.10 and Firefox ESR < 102.10.(CVE-2023-1945)

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.(CVE-2023-1999)

A website could have obscured the fullscreen notification by using a combination of <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and <code>setInterval</code> calls.
