exim4-daemon-heavy: Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges
CVE-2020-28008 is fixed in 6 products on 1 platform, first by exim4 4.90.1-1ubuntu1.8, released May 4, 2021. It is not reported as exploited. Patch Radar priority: Routine.
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.
