Exim 4 before 4.94.2 has Execution with Unnecessary Privileges.
MEDIUM 6.3EPSS 0.98%
Does this matter?
Lower severity and a low EPSS score (0.98%). Track it; it rarely justifies an emergency change on its own.
Description
Exim 4 before 4.94.2 has Execution with Unnecessary Privileges. By leveraging a delete_pid_file race condition, a local user can delete arbitrary files as root. This involves the -oP and -oPX options.
