A vulnerability in the Windows kernel can be triggered via SMB in Microsoft Windows versions ranging from Windows 2000 through to Windows 7. This vulnerability allows an attacker to trigger a kernel pool corruption by sending a specially crafted SMB_COM_TRANSACTION2 request. Successful exploitation of this issue may result in remote code execution with kernel privileges, while failed attempts will result in a denial of service condition.

Whitepaper that discusses types of computer worms and how metamorphic worms differ from the rest.

This Metasploit module exploits sendmail's well-known historical debug mode to escape to a shell and execute commands in the SMTP RCPT TO command. This vulnerability was exploited by the Morris worm in 1988-11-02. Cliff Stoll reports on the worm in the epilogue of The Cuckoo's Egg. Currently only cmd/unix/reverse and cmd/unix/generic are supported.

A vulnerability is present in AT&T TCP/IP Release 4.0 running on SVR4 systems for both the 386/486 and 3B2 RISC platforms. The problem is in the remote execution server /usr/etc/rexecd and a new version of rexecd is available from AT&T.
