Did gentoo use the wrong sendmail package??
All sendmail packages downloaded from the sendmail FTP site between 28th of september and 6th of October contain a trojan horse.

This is the CERT anouncement: http://www.cert.org/advisories/CA-2002-28.html


Just so you know!! I hope Gentoo comes with an update soon...

Sigh.

If you consult the ebuild for sendmail, you'll find that the MD5 sum that portage verifies the downloaded Sendmail against is the same as CERT gave out for the 'clean' build.

Trojaned packages would have failed MD5, and I *think* Portage would then have attempted to use another mirror. In fact, I think it would have been attempting to use a mirror in the first place ( ibiblio, for example ).

There is no need for an update.

Yeah, it's one of the cooler features of portage. :-)

apt (used by Debian and Conectiva) have signed packages. As long as you have the keys from the ditribution, you can check all packages and be sure they are OK.
