Package        : exim
Vulnerability  : buffer overflow
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2004-0399 CAN-2004-0400

Georgi Guninski discovered two stack-based buffer overflows.  They can
not be exploited with the default configuration from the Debian
system, though.  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.
