Edwin Groothuis reports in this FreeBSD Security Mailinglist post that the OpenSSH package on ftp.openbsd.org, and possibly all mirrors, is trojaned. Makefile.in has been modified, an generates a shell-script that tries to connect to 203.62.158.32:6667 (web.snsonline.net).

This is the md5 checksum of the openssh-3.4p1.tar.gz in the FreeBSD ports system:
MD5 (openssh-3.4p1.tar.gz) = 459c1d0262e939d6432f193c7a4ba8a8

This is the md5 checksum of the trojaned openssh-3.4p1.tar.gz:
MD5 (openssh-3.4p1.tar.gz) = 3ac9bc346d736b4a51d676faa2a08a57
