Debian GNU/Linux Advisory: exim

May 10, 2004, 20:57 (2 Talkback[s])

Debian Security Advisory DSA 501-1 security@debian.org
http://www.debian.org/security/ Martin Schulze
May 7th, 2004 http://www.debian.org/security/faq


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.
