CVE-2003-0161

High
Published: Translated: NVD NIST

Summary

The prescan() function in the address parser in Sendmail before version 8.12.9 does not properly handle conversions from char and int types, which can lead to a length check being disabled. This allows attackers to cause a denial of service and potentially execute arbitrary code via a buffer overflow attack.

Risk Assessment

The organization may be exposed to attacks that lead to denial of service and potential remote code execution, which can have serious security implications for the system.

Recommendation

It is recommended to update Sendmail to version 8.12.9 or later to mitigate this vulnerability and implement additional security measures to protect against buffer overflow attacks.

Original NVD description (English source)

The prescan() function in the address parser (parseaddr.c) in Sendmail before 8.12.9 does not properly handle certain conversions from char and int types, which can cause a length check to be disabled when Sendmail misinterprets an input value as a special "NOCHAR" control value, allowing attackers to cause a denial of service and possibly execute arbitrary code via a buffer overflow attack using messages, a different vulnerability than CVE-2002-1337.
