Double-free issues compromise memory integrity and are often a precursor to use-after-free or arbitrary code execution vulnerabilities, particularly in applications written in C/C++ that lack memory safety guarantees. In this case, the vulnerability occurs during encoder initialization for WebRTC, a high-frequency, remotely triggerable code path in browsers like Firefox. Because the failure happens after a failed allocation, it exposes a non-trivial edge case in error handling, which can be difficult to audit and reliably mitigate. The risk is elevated by the fact that WebRTC handles untrusted input from remote peers, making the flaw remotely exploitable in real-world scenarios.",

Details
A crafted HTML email using mailbox:/// links can trigger automatic, unsolicited downloads of .pdf files to the user's desktop or home directory without prompting, even if auto-saving is disabled. This behavior can be abused to fill the disk with garbage data (e.g. using /dev/urandom on Linux) or to leak Windows credentials via SMB links when the email is viewed in HTML mode. While user interaction is required to download the .pdf file, visual obfuscation can conceal the download trigger. Viewing the email in HTML mode is enough to load external content. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1.
