| Doc Text: |
An out-of-bounds read flaw was found in Exim which exists within the smtp service. 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, leading to disclosure of some sensitive information. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the service account.
