| Doc Text: |
An out-of-bounds write flaw exists in Exim 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 write past the end of a buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Authentication is not required to exploit this vulnerability.
