I have used the following steps and reproduced a tab crash: 1. Download and open build 2. Load the malicious webp image: https://bugzilla.mozilla.org/attachment.cgi?id=9352592 Actual: Tab crash. Expected: Tab does NOT crash. We have reproduced it on Windows 10 and Ubuntu 20 with Nightly v119.0a1 from 2023-09-11-09-18-54, Beta v118.0b7 asan, Release v117.0.1 build 1 and verified this fix in Nightly v119.0a1 from 2023-09-12-04-12-49, Beta v118.0b8, Release v117.0.1 build 2, ESR v115.3.0esr and ESR v102.15.1esr. Mac OS asan builds would not run so we could not reproduce or verify on MacOS.
