CVE-2024-11696 Information

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.
