CVE-2009-2466 2 Mozilla, Redhat 3 Firefox, Thunderbird, Enterprise Linux 2025-06-25 N/A
The JavaScript engine in Mozilla Firefox before 3.0.12 and Thunderbird allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) nsDOMClassInfo.cpp, (2) JS_HashTableRawLookup, and (3) MirrorWrappedNativeParent and js_LockGCThingRT.
CVE-2025-1936 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-06-24 7.3 High
jar: URLs retrieve local file content packaged in a ZIP archive. The null and everything after it was ignored when retrieving the content from the archive, but the fake extension after the null was used to determine the type of content. This could have been used to hide code in a web extension disguised as something else like an image. This vulnerability affects Firefox < 136, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8.
CVE-2024-11705 1 Mozilla 2 Firefox, Thunderbird 2025-06-24 9.1 Critical
`NSC_DeriveKey` inadvertently assumed that the `phKey` parameter is always non-NULL. When it was passed as NULL, a segmentation fault (SEGV) occurred, leading to crashes. This behavior conflicted with the PKCS#11 v3.0 specification, which allows `phKey` to be NULL for certain mechanisms. This vulnerability affects Firefox < 133 and Thunderbird < 133.
CVE-2024-11698 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2025-06-24 9.8 Critical
A flaw in handling fullscreen transitions may have inadvertently caused the application to become stuck in fullscreen mode when a modal dialog was opened during the transition. This issue left users unable to exit fullscreen mode using standard actions like pressing "Esc" or accessing right-click menus, resulting in a disrupted browsing experience until the browser is restarted. *This bug only affects the application when running on macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5.
CVE-2024-11696 2 Mozilla, Redhat 9 Firefox, Firefox Esr, Thunderbird and 6 more 2025-06-24 5.4 Medium
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.
CVE-2024-11694 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-06-24 6.1 Medium
Enhanced Tracking Protection's Strict mode may have inadvertently allowed a CSP `frame-src` bypass and DOM-based XSS through the Google SafeFrame shim in the Web Compatibility extension. This issue could have exposed users to malicious frames masquerading as legitimate content. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Firefox ESR < 115.18, Thunderbird < 133, Thunderbird < 128.5, and Thunderbird < 115.18.
