Exim < 4.72 Multiple Vulnerabilities
Medium Nessus Network Monitor Plugin ID 5557
Synopsis
The remote mail server is vulnerable to multiple attack vectors.
Description
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)
Solution
Upgrade to Exim 4.72 or later when it becomes available.
