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 3.35-3woody2. 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. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
