The Common Vulnerabilities and Exposures project identifies the following problems that are fixed with this update:

CAN-2004-0399

When 'sender_verify = true' is configured in exim.conf a buffer overflow can happen during verification of the sender. This problem is fixed in exim 4.

CAN-2004-0400

When headers_check_syntax is configured in exim.conf a buffer overflow can happen during the header check. This problem does also exist in exim 4.

For the stable distribution (woody) these problems have been fixed in version 3.35-1woody3.

For the unstable distribution (sid) these problems have been fixed in version 3.36-11 for exim 3 and in version 4.33-1 for exim 4.

We recommend that you upgrade your exim package.");
