Exim < 4.72 Multiple Vulnerabilities



The remote mail server is vulnerable to multiple attack vectors.


The remote host is running Exim, a message transfer agent.

Versions of Exim earlier than 4.72 are potentially affected by multiple vulnerabilities :

- An error when handling hardlinks within the mail directory during the email delivery process can be exploited to perform unauthorized actions. (CVE-2010-2023)

- When MBX locking is enabled, a race condition exists which could allow an attacker to change permissions of other non-rot users' files, leading to denial-of-service conditions or potentially privilege escalation. (CVE-2010-2024)


Upgrade to Exim 4.72 or later when it becomes available.
