The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-a2c6c8afa9 advisory.
A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4367)
Multiple WebRTC threads could have claimed a newly connected audio input leading to use-after-free. This vulnerability affects Firefox < 126. (CVE-2024-4764)
Web application manifests were stored by using an insecure MD5 hash which allowed for a hash collision to overwrite another application’s manifest. This could have been exploited to run arbitrary code in another application’s context. This issue only affects Firefox for Android. Other versions of Firefox are unaffected. This vulnerability affects Firefox < 126. (CVE-2024-4765)
Different techniques existed to obscure the fullscreen notification in Firefox for Android. These could have lead to potential user confusion and spoofing attacks. This bug only affects Firefox for Android.
Other versions of Firefox are unaffected. This vulnerability affects Firefox < 126. (CVE-2024-4766)
If the browser.privatebrowsing.autostart
preference is enabled, IndexedDB files were not properly deleted when the window was closed. This preference is disabled by default in Firefox. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4767)
A bug in popup notifications’ interaction with WebAuthn made it easier for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4768)
When importing resources using Web Workers, error messages would distinguish the difference between application/javascript
responses and non-script responses. This could have been abused to learn information cross-origin. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4769)
When saving a page to PDF, certain font styles could have led to a potential use-after-free crash. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4770)
A memory allocation check was missing which would lead to a use-after-free if the allocation failed. This could have triggered a crash or potentially be leveraged to achieve code execution. This vulnerability affects Firefox < 126. (CVE-2024-4771)
An HTTP digest authentication nonce value was generated using rand()
which could lead to predictable values. This vulnerability affects Firefox < 126. (CVE-2024-4772)
When a network error occurred during page load, the prior content could have remained in view with a blank URL bar. This could have been used to obfuscate a spoofed web site. This vulnerability affects Firefox < 126. (CVE-2024-4773)
The ShmemCharMapHashEntry()
code was susceptible to potentially undefined behavior by bypassing the move semantics for one of its data members. This vulnerability affects Firefox < 126. (CVE-2024-4774)
An iterator stop condition was missing when handling WASM code in the built-in profiler, potentially leading to invalid memory access and undefined behavior. Note: This issue only affects the application when the profiler is running. This vulnerability affects Firefox < 126. (CVE-2024-4775)
A file dialog shown while in full-screen mode could have resulted in the window remaining disabled. This vulnerability affects Firefox < 126. (CVE-2024-4776)
Memory safety bugs present in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4777)
Memory safety bugs present in Firefox 125. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 126. (CVE-2024-4778)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
