06 May 2021 — Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the spool directory (owned by a non-root user), an attacker can write to a /var/spool/exim4/input spool header file, in which a crafted recipient address can indirectly lead to command execution. Exim 4 versiones anteriores a 4.94.2, permite una ejecución con Privilegios Innecesarios.
