Re: <Advice> Possible Backdoor into openssh-3.7.1p1-i386-1.tgz from Slackware Mirror

Hi,

Hello
 
I have update my Slackware 9.0 with openssh-3.7.1p1-i386-1.tgz  from
http://www.slackware.at/data/slackware-9.0/patches/packages/openssh-3.7.1p1-i386-1.tgz

Now i have 3 new  tcp/ip ports into my system: (thank Nmap) :-)

- 867 Open
- 879 Open
- 889 Open

Example:

telnet> open
(to) 127.0.0.1 867
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

These ports are choice random from a range of  300 - 1200 !! and the size of
the tgz is various for every mirror:

628642 Sep 20 17:58 openssh-3.7.1p1-i386-1.tgz (from www.slackware.at)
628481 Sep 20 21:01 openssh-3.7p1-i386-1.tgz   (from www.slackware.com)

Odd. That's not what I get when I ftp to ftp.slackware.com and 
ftp.slackware.at These are my results:

ftp.slackware.com:
ncftp ...e-9.0/patches/packages > ls -al openssh-3.7.1p1-i386-1.tgz
-rw-r--r--   1 volkerdi users      628642 Sep 17 01:24 
openssh-3.7.1p1-i386-1.tgz
ncftp ...e-9.0/patches/packages > pwd
ftp://ftp.slackware.com/pub/slackware/slackware-9.0/patches/packages/


ftp.slackware.at
ncftp ...e-9.0/patches/packages > ls -al openssh-3.7.1p1-i386-1.tgz
-rw-r--r--   1 slack    slack      628642 Sep 17 08:24 
openssh-3.7.1p1-i386-1.tgz
ncftp ...e-9.0/patches/packages > pwd
ftp://ftp.slackware.at/slackware-9.0/patches/packages/
 
So, same size for me. I've also checked ftp.gentoo.no which keeps mirrors 
of slackware.com, and the size is the same there
