CVE-2004-0400
HighSummary
A stack-based buffer overflow exists in Exim 4 before version 4.33 when the headers_check_syntax option is enabled. This allows remote attackers to cause a denial of service and potentially execute arbitrary code during the header check.
Risk Assessment
The organization may experience service outages and the risk of malicious code execution, potentially leading to data loss or system compromise.
Recommendation
It is recommended to update Exim to version 4.33 or later and to disable the headers_check_syntax option if it is not necessary.
