Debian DSA-502-1 : exim-tls - buffer overflow

high Nessus Plugin ID 15339

Synopsis

The remote Debian host is missing a security-related update.

Description

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 :

 - 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.

Solution

Upgrade the exim-tls package.

For the stable distribution (woody) these problems have been fixed in version 3.35-3woody2.
