  script_tag(name:"insight", value:"Georgi Guninski discovered two stack-based buffer overflows in exim
and exim-tls.  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:

CVE-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.

CVE-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 3.35-3woody2.

The unstable distribution (sid) does not contain exim-tls anymore.
The functionality has been incorporated in the main exim versions
which have these problems fixed in version 3.36-11 for exim 3 and in
version 4.33-1 for exim 4.");
