Debian DSA-501-1 : exim - buffer overflow

high Nessus Plugin ID 15338

Synopsis

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

Description

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.

Solution

Upgrade the exim package.

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