Many users already upgraded APT in a vulnerable way without ever knowing
about this issue.
What about introducing a security on/off switch that a subset of Qubes
developers can trigger?
Before apt-get (or other package manager) does actually anything, a
simple script could fetch a file from Qubes clearnet domain (and/or
onion) and ask "is it currently secure to update"?
In most cases, the server would provide a cryptographically signed file
by a Qubes developer which says "ok". Otherwise in situations such as
now with APT security vulnerability DSA 4371-1 a Qubes developer could
put a cryptographically signed file saying "not safe" there. In such
cases, updates would be blocked until a new file is provided.
Things to keep in mind related to such a file: man-in-the-middle attack
- infinite freeze atttacks; rollback attacks; perhaps more. Can think
about this more if this sounds interesting.
Of course there should be options to:
- disable this mechanism entirely
- manually override by user
These override option is useful for:
- to stay flexible in case of bugs of this mechanism itself and,
- to not give Qubes developers too much power. No advanced adversary
should be able to ask Qubes developers to remotely brick all Qubes
installations (mostly theoretic at this point and not important for now
but still easy to implement and good to have),
- other unforeseeable things.
This idea could be seen as a subset of the emergency project news
mechanism that is currently missing in all distributions. In short:
distributions have no mechanism to communicate with their users
effectively in situations such as this one. More info:

“Look here!” Dick began to chuckle. “We’ve got a queer combination to work with—our Sky Patrol has! Suspicious Sandy—and—Superstitious Jeff!” Sandy grinned ruefully, a little sheepishly. Larry smiled and shook his head, warning Dick not to carry his sarcasm any further, as Jeff frowned. 52 "You do doubt me. If you did not, it would never occur to you to deny it. You doubt me now, and you will doubt me still more if you don't read it. In justice to me you must." "That same. She was part Mescalero, anyway." This Act, as disgraceful as any which ever dishonoured the statute-book in the reigns of the Tudors or Stuarts, was introduced into the Commons, on the 12th of May, by Sir William Wyndham, and was resolutely opposed by the Whigs, amongst whom Sir Peter King, Sir Joseph Jekyll, Mr. Hampden, Robert Walpole, and General Stanhope distinguished themselves. They did not convince the majority, which amounted to no less than two hundred and thirty-seven to one hundred and twenty-six. In the Lords, Bolingbroke himself moved the second reading, and it was ably opposed by the Lords Cowper, Wharton, Halifax, Townshend, Nottingham, and others. The greatest curiosity was displayed regarding the part which Oxford would take, as it was known that in the Council he had endeavoured to soften the rigorous clauses; but in the House he followed his usual shuffling habit, declaring that he had not yet considered the question; and, having induced the Opposition to let the second reading pass without a division, he absented himself from the final voting, and thus disgusted both parties and hastened his own fall. The battle of Falkirk, which in itself appeared so brilliant an affair for Prince Charles, was really one of his most serious disasters. The Highlanders, according to their regular custom when loaded with plunder, went off in great numbers to their homes with their booty. His chief officers became furious against each other in discussing their respective merits in the battle. Lord George Murray, who had himself behaved most bravely in the field, complained that Lord John Drummond had not exerted himself, or pursuit might have been made and the royal army been utterly annihilated. This spirit of discontent was greatly aggravated by the siege of the castle of Stirling. Old General Blakeney, who commanded the garrison, declared he would hold out to the last man, in spite of the terrible threats of Lord George Murray if he did not surrender. The Highlanders grew disgusted with work so contrary to their habits; and, indeed, the French engineer, the so-called Marquis de Mirabelle, was so utterly ignorant of his profession, that the batteries which he constructed were commanded by the castle, and the men were so much exposed that they were in danger of being destroyed before they took the fortress. Accordingly, on the 24th of January they struck to a man, and refused to go any more into the trenches. "Haint we bit off more'n we kin chaw. Shorty?" asked Si, as he looked over the increasing gang. "Hadn't we better ask for some help?" "How far would it carry?" Corpril, Company Q, 2 Hundsrdth Injiamiy Volintear "He d?an't care much. F?ather, he likes to be comfortable, and this Inclosure w?an't make much difference to that. 'T?un't as if we wanted the pasture badly, and F?ather he d?an't care about land." "Byles," interrupted Calverley, speaking rapidly, "you are poor—you are in arrear with your rent; a distress will be levied, and then what will become of you—of your wife and the little one? Listen to me! I will give you money to keep a house over your head; and when I am steward, you shall have the first farm at my lord's disposal, if you will only aid me in my revenge! Revenge!" he repeated, vehemently—"but you hesitate—you refuse." "Yes, yes, there is little doubt of that: but how can we come at the truth? Sudbury still retains his wrath against us, and would oppose an arrest; and even could he be waylaid, and brought hither, he is stubborn, and might refuse to answer." HoME一级做人爱c视正版免费
