Re: [SECURITY] [DSA 479-2] New Linux 2.4.18 packages fix local root exploit (i386)
Hi,
I got the mail, and happy to know that you keep the good work. But when I
did 'apt-get update', there was no change in http://security.debian.org
files. Is it possible to make sure the files are updated before sending the
announcement?
I know that each mail has the link for all the files... but many people
automate the updates of the machine, which means that they won't get the
updates till the mirror files will be updated.
Regards,
Lior Kaplan
