Title text: CVE-2018-?????: It turns out Bruce Schneier is just two mischevious kids in a trenchcoat.

Explanation

Ambox notice.png This explanation may be incomplete or incorrect: Created by a BOT - The explanation looks like a list. Explain the comic and put the security vulnerabilities in a table. Do NOT delete this tag too soon.

CVE stands for Common Vulnerabilities and Exposures : a list of bugs detected in software and hardware, this list is the equivalen of the meme of "Memes of 2018 leaked"

Apple Products Crash refers to a current vulnerability in Macos and iphone This new text bomb crashes most Mac and iOS apps with a single Unicode symbol (techcrunch.com FEb 15, 2018)

Timing Attack to explit a race condition in garbaje collection refers to Meltdown and Spectre CPU flaws that can be exploited in cloud server like the ones in wikipedia

Post it note on a cafe refers to the hawaian missile alert incident

Remote attacker can inject can refer to a lot of scriptkiddies utilities to realice code injection, is something common in websites

MySQL server 5.5.45 parallel tables (unknow)

Flaw in some X86 CPU: refers to DOM0 attacks on Virtualization CPUs, regulary escalate from normal(few privileges) to root (full privileges), this is the inverse.

Apple products catch fire: Mix between the first CVE and the Samnsung exploding phones

Dog in basebal team likely refers to the movie Air Bud. It's a movie about a dog playing basketball [[1]]

Haskell is a functional programing languaje, funcional programing is characterized by using functions that dont have side effects in other parts of the program.

Nobody Knows how hypervisors work : Virtualization programing is hard, Meltdown and Specter are related to this

CRITICAL: Under Linux 3.14.8 OnSystem/390: jokes about arcane systems that are running linux, that have bugs that nobody can replicate because there are no more machines on this type where reproduce the bug to fix it.

x86 has way too many instructions: there are a joke account for random acronyms of processor assembled languaje many of them are overspecialized version of general ones

Numpy 1.8.0 can factor primes in O( Log(N)) : NumPy is the fundamental package for scientific computing with Python. If something can factor primes that fast, there are attacks to break many crypto functions used in internet security, then must be deprecated because there are not replacements


Apple products grant remote access if you send : another joke on the first CVE and a common english write rule

Skylake x86 chips are a line of microprocesors, yes, you can remove forcefully any procesador from his socket with a screwdriver , there are many reports from people not using common sense.

Linux Torvals is the benebolent dictator of the Linux kernel codebase, normally is hard to pass a change because he has the last word about what merge to the code base because that code is replicated in all linux instalations, but apparently is easy to bribe, that is a severe creitical vulnerability to all linux server and machines


"An attacker can excecute malicious code .. " is a common CVE description

Apple products excute any code printed over a photo , can refer to a CVE vulnerability of JPG files where javascript is executed by some application, only this time is in a printed photo instead of a file .


"Under rare circunstances, a flaw ... " is another common CVE description, Flash was discontinued because is abismal security record. All security experts advise against install.

"Turns out the cloud is just another peopleś computer" refers to a computer meme where replace "cloud" with "another peopleś computer" must be used in all marketing presentation to CEOs and not computer literate persons to evaluate the security impact of using "Cloud services"


Mitress CVE database is the database where all CVE are listed, this is a joke between the 4th CVE in this list pointing that the site is also vulnerable

CVE-2018-????? Nobody really knows how hypervisors work.

CVE-2018-????? CRITICAL: Under Linux 3.14.8 on System/390 in a UTC+14 time zone, a local user could potentially use a buffer overflow to change another user's default system clock from 12-hour to 24-hour.
