CVE-2024-11696 Security feature bypass in Firefox

What is CVE-2024-11696?

CVE-2024-11696 is a medium-severity vulnerability in Mozilla Firefox, published on 26 Nov 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

The application failed to account for exceptions thrown by the `loadManifestFromFile` method during add-on signature verification. This flaw, triggered by an invalid or unsupported extension manifest, could have caused runtime errors that disrupted the signature validation process. As a result, the enforcement of signature validation for unrelated add-ons may have been bypassed. Signature validation in this context is used to ensure that third-party applications on the user's computer have not tampered with the user's extensions, limiting the impact of this issue. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5.
