    Multiple security issues have been found in the Mozilla Firefox web     browser, which could potentially result in the execution of arbitrary     code, information disclosure or privilege escalation.

    For the stable distribution (trixie), these problems have been fixed in     version 140.16.0esr-1~deb13u1.
