'Stack Clash' Linux Flaw Enables Root Access. Patch Now

1 Comment
msm1267 writes: Linux, BSD, Solaris and other open source systems are vulnerable to a local privilege escalation vulnerability known as Stack Clash that allows an attacker to execute code at root. Major Linux and open source distributors made patches available Monday, and systems running Linux, OpenBSD, NetBSD, FreeBSD or Solaris on i386 or amd64 hardware should be updated soon. The risk presented by this flaw, CVE-2017-1000364, becomes elevated especially if attackers are already present on a vulnerable system. They would now be able to chain this vulnerability with other critical issues, including the recently addressed Sudo vulnerability, and then run arbitrary code with the highest privileges, said researchers at Qualys who discovered the vulnerability.

Japanese robot sumo wresting is incredibly fast

2 Comments and 5 Shares

Robots fighting each other in arenas is a popular sporting event; see Robot Wars. In Japan, such competitions often take place in small sumo rings and the robots need to move incredibly fast to achieve victory. Robert McGregor compiled some of the fastest and most vicious footage in this video…and none of the footage is sped up in any way. Note the protective leg pads worn by the referee in many of the clips…there must have been an “incident”. (via @domyates)

NASA Apollo Saturn V Lego set

Apollo 11 Lego

Lego has introduced an Apollo Saturn V rocket set, complete with lunar lander and 3 astronaut minifigs.

Packed with authentic details, it features 3 removable rocket stages, including the S-IVB third stage with the lunar lander and lunar orbiter. The set also includes 3 stands to display the model horizontally, 3 new-for-June-2017 astronaut microfigures for role-play recreations of the Moon landings, plus a booklet about the manned Apollo missions and the fan designers of this educational and inspirational LEGO Ideas set.

Three rocket stages! And look at this lander:

Amazing detail: the set contains 1969 pieces, which is the year that the Apollo 11 astronauts landed on the Moon. I typically leave the Lego building to my kids, but I might have to make an exception for this. (via mike)

What bullets do to bodies

2 Comments and 11 Shares

Emergency room doctor Leana Wen writes in the NY Times about what bullets do to human bodies.

Early in my medical training, I learned that it is not the bullet that kills you, but the damage from the bullet. A handgun bullet enters the body in a straight line. Like a knife, it damages the organs and tissues directly in its path, and then it either exits the body or is stopped by bone, tissue or skin.

This is in contrast to bullets from an assault rifle. They are three times the speed of handgun bullets. Once they enter the body, they fragment and explode, pulverizing bones, tearing blood vessels and liquefying organs.

Earlier this year, Jason Fagone wrote a much longer piece on the same topic for HuffPost.

“As a country,” Goldberg said, “we lost our teachable moment.” She started talking about the 2012 murder of 20 schoolchildren and six adults at Sandy Hook Elementary School. Goldberg said that if people had been shown the autopsy photos of the kids, the gun debate would have been transformed. “The fact that not a single one of those kids was able to be transported to a hospital, tells me that they were not just dead, but really really really really dead. Ten-year-old kids, riddled with bullets, dead as doornails.” Her voice rose. She said people have to confront the physical reality of gun violence without the polite filters. “The country won’t be ready for it, but that’s what needs to happen. That’s the only chance at all for this to ever be reversed.”

She dropped back into a softer register. “Nobody gives two shits about the black people in North Philadelphia if nobody gives two craps about the white kids in Sandy Hook. … I thought white little kids getting shot would make people care. Nope. They didn’t care. Anderson Cooper was up there. They set up shop. And then the public outrage fades.”

I think about this tweet all the time:

In retrospect Sandy Hook marked the end of the US gun control debate. Once America decided killing children was bearable, it was over.

That tweet gets me every time I see it. I am dumbfounded that American love for guns is greater than anything else.

Guns are a powerful symbol for perceived freedom. And freedom is embedded in the national psyche of America. To take away guns represents a notch down in perceived freedom. It's not logical. It's not rational.

Car fact of the day

Twenty years ago, cars had, on average, one million lines of code. The General Motors 2010 Chevrolet Volt had about 10 million lines of code — more than an F-35 fighter jet.

Today, an average car has more than 100 million lines of code. Automakers predict it won’t be long before they have 200 million.

That is from Nicole Perlroth at the NYT.
