Detail
| Georgi Guninski discovered two stack-based buffer overflows in exim and exim-tls. 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. |

| Id | Description |
|---|---|
| 5897 | Exim header_syntax Function Remote Overflow A remote overflow exists in Exim. The issue is due to a boundary error within a routine for header syntax checking resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of confidentiality and integrity. |
| 5896 | Exim sender_verify Function Remote Overflow A remote overflow exists in Exim. The issue is due to a boundary error within the verification of sender addresses resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code execution resulting in a loss of confidentiality and integrity. |
