[DSA502] DSA-502-1 exim-tls Vulnerability Scan

Vulnerability Scan Summary
DSA-502-1 exim-tls

Detailed Explanation for this Vulnerability Test

Georgi Guninski discovered two stack-based buffer overflows in exim
and exim-tls. They cannot 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:
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.


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.
We recommend that you upgrade your exim-tls package.
