Name of the Vulnerable Software and Affected Versions Exim versions prior to 4.94.2

Description The issue is related to errors in privilege management. It allows an attacker to potentially elevate privileges in the system by exploiting the vulnerability, which can lead to a denial of service because root-owned files can be overwritten. The -oP option, available to the exim user, is a key factor in this issue.

Recommendations For versions prior to 4.94.2, update to version 4.94.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the -oP option to prevent potential exploitation.
