Debian Developers:

Given how trivial it is to crack eMudhra's certs[1], isn't HTTPS useless as a
mitigation[2] for CVE-2026-109518[3] wrt new installations? It's bad enough
that new ISOs for 26.10 and 26.04 LTS weren't released following the cert
compromise, but given the APT vuln, any coffee shop skid or ISP technician can
trivially pwn a new installation of Debian *at first upgrade time*. Having
unattended-upgrades enabled by default actually makes this *far worse*, since
users are likely to have their system autoupgrade 24 hours after installation,
*without* `-o Acquire::Retries=0` set!  Considering the rate at which users are
migrating away from Winglows 11 to GNU+Linux, the number of new Debian laptop
users is surely growing all the time.

Not to mention: The number of sysadmins who rely on (whether by choice or
corporate policy) Debian for their server installations is always high, and
your cloud images[4] still ship a vulnerable APT.

Isn't it also the case that, if a mirror *itself* is compromised or simply
outright malicious, HTTPS alone doesn't mitigate this issue?  Isn't it most
trivial of all for a mirror itself to force retries of failed downloads,
thereby totally bypassing PGP signature verification of packages? US citizens,
and, more broadly speaking, citizens of the 5EYES, should be incredibly
concerned by this given Debian's governing jurisdiction. The default GeoIP
mirrors for new installations of Debian are, themselves, a threat to US users
of Debian at installation time at present.

And why the hell is it that I can find zero mitigation instructions published
by Debian for the APT vuln? The advice from Debian seems to more or less just
be "Upgrade as usual. Nothing to see here! See? We secured your operating
system for you!" That, of course, is imbecilic advice—admittedly given only by
implication of your silence on this matter, but the silence is truly deafening
in this case. Ubuntu's blog actually provides the necessary steps to mitigate
the vuln at time of package upgrades. Why did I need to check a derivative
distribution's blog to find this? Your blog and microblog don't even mention
the vulnerability at all. The mailing list thread documenting the upgrade to
apt doesn't even document the steps to mitigate the vuln when upgrading apt
itself!

Why was there no new ISO released following the cert compromise? Why is there
still no installation media now, following the fix of this critical APT vuln?
It's not just you, either. Ubuntu's just as bad! Are you both completely
compromised by glowies at this point??

Unkind regards,
Elven Inquisition
