An out-of-bounds read vulnerability was found in Exim within the handling of NTLM challenge requests. 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 data structure. An attacker can leverage this vulnerability to disclose information in the context of the service account. Authentication is not required to exploit this vulnerability.
