Subject: Re: [RHSA-2003:279-01] Updated OpenSSH packages fix potential vulnerability


Recent security advisories featuring the operating system known as
'GNU/Linux' (formerly minix) has had a negative effect on the
listserv.

The problem stems from the polymorphic, virus-like phenomenon also
known as the 'Linux distro', the Linux distro allows any single
permutation of a base Linux install (such as location of the mail
spool) to actually qualify and require an entire new operating
system distribution.  At this point in time there are over 50
distros out there.

The cascade failure effect is that the minute a hole or flaw in a
base Linux subsystem such as the kernel or system tools immediately
causes a flood of 'vendor' emails sent to bugtraq describing each
way to disable/upgrade the broken feature on their OS.

The effect is that the 'signal to stupid-linux-bug ratio' on the
lists gets completely out of whack thereby diluting the utility
of the list.

Solutions:

  None. (how do you expect to stop a tidal wave of suicidal VC money?)

Workarounds:

1) All advisories should be filtered through RMS, which would achieve
   the desired effect of delaying their posting indefinitely.
2) All such advisories should be prefixed by '[YASLB]' in the subject line
   (yet another stupid linux bug) so I can filter this stupid crap.

thanks,
everyone
