EIP-2026-102645

This exploit targets a denial-of-service vulnerability in Sendmail (2.0.x kernels) by sending spoofed TCP SYN packets followed by RST packets, causing the Sendmail daemon to loop indefinitely. The code constructs raw IP packets with a SYN flag and sends them to the target, exploiting the quirk in the TCP implementation where accept() returns after a SYN is received.
