Name of the Vulnerable Software and Affected Versions
Exim (affected versions not specified)
Description
The issue is related to an out-of-bounds read in the Exim smtp service, which can allow network-adjacent attackers to disclose sensitive information on affected installations of Exim. The specific flaw exists within the smtp service, which listens on TCP port 25 by default. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the service account.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
