Mozilla: Sandbox escape through Firefox Sync

Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the...

UBUNTU-CVE-2019-11741

A compromised sandboxed content process can perform a Universal Cross-site Scripting UXSS attack on content from any site it can cause to be loaded in the same process. Because addons.mozilla.org and accounts.firefox.com have close ties to the Firefox product, malicious manipulation of these site...

Arbitrary Code Execution

Firefox and Firefox ESR are vulnerable to arbitrary code execution attacks. A remote user could trigger a bailout error in the JavaScript JIT compiler when inlining 'Array.prototype.push' to potentially execute arbitrary code within the sandboxed content process which may lead to disclosure of...

CVE-2019-9802

If a Sandbox content process is compromised, it can initiate an FTP download which will then use a child process to render the downloaded data. The downloaded data can then be passed to the Chrome process with an arbitrary file length supplied by an attacker, bypassing sandbox protections and all...
