Description

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.

Solution(s)

  • ubuntu-upgrade-exim4-base
  • ubuntu-upgrade-exim4-daemon-heavy
  • ubuntu-upgrade-exim4-daemon-light
