Exploitation Summary
EIP tracks 2 public exploits for CVE-2003-0161. PoCs published by bysin, sorbo.
AI-analyzed exploit summary This exploit targets a buffer overflow vulnerability in Sendmail 8.12.8 and below via the prescan() function. It crafts a malicious RCPT TO command to trigger a segmentation fault, demonstrating the vulnerability.
Description
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.
