Another Reason to Boycott UEFI and Proprietary Software From Microsoft: Insecurity

Posted in Microsoft, Security at 12:27 pm by Dr. Roy Schestowitz

Summary: Some blobs like Microsoft’s Windows patches and the binary-level UEFI ‘validation’ do not and cannot provide real security, only insecurity in disguise

THE ‘PROMISE’ of UEFI ‘secure’ boot is as ludicrous as Microsoft's claims that it pursues security. UEFI does nothing real for security; in fact, it once again does the very opposite. Quoting the news:

A pair of security researchers have found a buffer overflow vulnerability within the implementation of the unified extensible firmware interface (UEFI) within the EDK1 project used in firmware development.

Bromium researcher Rafal Wojtczuk and MITRE Corp’s Corey Kallenberg said the bug in the FSVariable.c source file was linked to a variable used to reclaim empty space on SPI flash chips.

According to other news, as told (spun) by a Microsoft booster.,”Microsoft’s advance security notification service no longer publicly available”. The booster says that “Microsoft is taking its Advance Notification Service private, claiming the change is due to changes in the way users want their advance security notifications.” Microsoft sure
tells the NSA about ways to hijack/wiretap Microsoft software, so it’s a matter of privilege, not some company-wide policy.

How does the above serve users? It doesn’t. This is about Microsoft, not users. Users will be left even more vulnerable. As Pogson correctly points out, “There are no Patch Tuesdays with Debian GNU/Linux so the bad guys are no further ahead. We can all get Debian’s patches as soon as they generate them and we can usually install the updates on running systems with no adverse consequences, like a re-re-reboot.”

Moreover, in large corporations in particular, patching code internally is possible or even relying on third parties. Don’t ever trust security at binary level, such as large blobs being sent that are supposedly ‘patched’ or some opaque board giving ‘approval’ before the running of a binary blob, mostly likely based on some cryptic signature approved by unknown people for unknown reasons (usually employees of companies that work with the NSA). Real security emanates from transparency, which breeds trust and provides to ability for one to study and patch one’s own programs (or rely on others to do so using their specialised skills).

“Anyone wonder why the Microsoft SQL server is called the sequel server? Is that because no matter what version it’s at there’s always going to be a sequel needed to fix the major bugs and security flaws in the last version?”

    Software patents are fast becoming a dying breed and the appeal board (PTAB) of the USPTO accelerates this trend, irrespective of patent immunity attempts



  3. No, China Isn't Most Innovative, It's Just Granting a Lot of Low-Quality Patents

    Patent extremists are trying to make China look like a role model or a success story because China grants far too many patents, spurring an explosion in litigation



  4. Battistelli-Campinos Transition Will Be a Smooth One as the Administrative Council Remains the Same and the Boards Still Besieged

    A rather pessimistic (albeit likely realistic) expectation from tomorrow's meeting of the Administrative Council, which continues to show that no lessons were learned and no strategy will be altered to avoid doom (low-quality patents and stocks running out)

    EPO-Handelsblatt attention diversion tricks may be effective as German media barely shows interest in one of the EPO's biggest scandals to date



  7. PTAB Haters Fail to Guard Bogus Patents, But They Still Try

    Three Affiliated Tribes probably won't enjoy sovereign immunity from PTAB, Dennis Crouch won't manage to slow down PTAB, and patent litigation will stagnate as bad patents perish before they even land in a lawsuit



  8. Team UPC's Tilmann Defends Rogue Vote at 1 AM in the Morning With Just 5% of Politicians (Those With Vested Interests) Attending

    Just when German democracy is being stolen by a legislative coup (in the dead of night when 95% of politicians are absent/asleep) there's someone 'courageous' enough to rear his ugly head and attempt to justify that coup



  9. The Mask Falls: Lobbyist David Kappos Now Composes Pieces for the Patent Trolls' Lobby (IAM)

    David Kappos, a former USPTO Director who is now lobbying for large corporations that derive revenue from patent extortion, is writing for IAM even if his views are significantly biased by his aggressive paymasters (just like IAM's)



  10. The EPO Protest Tomorrow Isn't Just About Judge Corcoran But About the EPO as a Whole

    PO staff is about to protest against the employer, pointing out that "Battistelli is still showing a total and utter lack of respect not only for his staff and their rights but also for the Administrative Council and for the Tribunal"



  11. Claim: Judge Corcoran to Be Put Under Benoît Battistelli's Control in DG1

    Benoît Battistelli, who openly disregards and refuses to obey judges (while intervening in trials and delivering 'royal decrees' whenever it suits him), may soon gain direct control over the judge he hates most



  12. The European Patent Organisation Refrains (For Nearly a Week) From Speaking About Battistelli's Abuses as Judged by ILO Tribunal

    The EPO's silence on the matter of Patrick Corcoran is deafening; to make matters worse, the EPO continues to pollute media and academia with money of stakeholders, with the sole intention of lobbying and misleading news coverage (clearly a disservice to these stakeholders)



  13. Carl Josefsson Lets Judge Patrick Corcoran Come Back to Work at the EPO

    After initial reluctance to obey/respect the rulings from the ILO (security staff declining access) there is official permission for Patrick Corcoran to enter and resume work (following 3 years of injustice against him)

    There are several indications that Microsoft-connected shells, which produce no products and are threatening a large number of companies, are inadvertently if not intentionally helping Microsoft sell "indemnification" ("Azure IP Advantage," which echoes the Microsoft/Novell strategy for collecting what they called "patent royalties" one decade ago)



  20. Yes, RPost is Definitely a Patent Troll and Its Software Patents Are at Risk Thanks to Alice

  25. Next Director of the USPTO Parrots Talking Points of Patent Extremists and Their Lobbyists

    The next USPTO boss (still subject to official confirmation) may be little more than a power grab by the litigation and patenting 'industry', which prioritises not science and technology but its own bottom line



  26. Raw: Three Years for 'Justice' (to be Disregarded by Benoît Battistelli) at ILO and Over a Decade at the EPO

    The delays associated with ‘justice’ at the EPO (usually neither justice nor compliance with rulings) have become so extraordinary that immunity should long ago have been stripped off and Battistelli et al been held accountable



  27. Raw: Scuttling of the General Advisory Committee and Battistelli Stacking the Deck to Have 'Yes Men' as Representatives

    How the EPO broke down resistance to Battistelli’s oppressive policies not only at the Council, disciplinary committees and auditory divisions but also staff representation (symptomatic of Battistelli’s notion of justice)
