CVE-1999-1529

This is a functional exploit for CVE-1999-1529, targeting a buffer overflow in the HELO command of the InterScan VirusWall SMTP gateway. The assembly code constructs a malicious payload to achieve remote code execution (RCE) by overflowing the buffer with NOP sleds and shellcode.

This Perl script exploits a buffer overflow in the HELO command of the InterScan VirusWall SMTP gateway (versions 3.32 builds 1011 and 1022). It sends a crafted HELO command with 4075 'a' characters to trigger a DoS or potential RCE, depending on the system configuration.
