'Severe Bug' To Be Patched In OpenSSL

Tue, 07 Jul 2015 17:25:00

An anonymous reader writes: The Register reports that upcoming OpenSSL versions 1.0.2d and 1.0.1p are claimed to fix a single security defect classified as "high" severity. It is not yet known what this mysterious vulnerability is — that would give the game away to attackers hoping to exploit the hole before the patch is released to the public. Some OpenSSL's examples of "high severity" vulnerabilities are a server denial-of-service, a significant leak of server memory, and remote code execution. If you are a system administrator, get ready to patch your systems this week. The defect does not affect the 1.0.0 or 0.9.8 versions of the library.

Switzerland Begins Trials of Expensive Postal Drones

Tue, 07 Jul 2015 16:27:00

An anonymous reader writes: Swiss Post has beat Amazon, Alibaba and other researchers into drone-based delivery by launching practical drops using a Matternet four-rotored drone this month. However the company says that five years of testing and negotiation with regulators lie ahead before it will be able to offer a commercial drone-based delivery service. Like Google's Project Wing, the Matternet drone in question is mooted as a potential lifeline in post-disaster situations, but from a business point of view the release notes its potential for 'express delivery of goods' — a further indicator that the future of postal drone delivery may be an exclusive and expensive one.

Crypto Experts Blast Gov't Backdoors For Encryption

Tue, 07 Jul 2015 15:46:00

loid_void writes with a link to a New York Times report about some of the world's best-known cryptography experts, who have prepared a report which concludes that there is

no viable technical solution which "would allow the American and British governments to gain "exceptional access" to encrypted communications without putting the world's most confidential data and critical infrastructure in danger." From the article:

[T]he government’s plans could affect the technology used to lock financial institutions and medical data, and poke a hole in mobile devices and the countless other critical systems — including pipelines, nuclear facilities, the power grid — that are moving online rapidly. ...

“The problems now are much worse than they were in 1997,” said Peter G. Neumann, a co-author of both the 1997 report and the new paper, who is a computer security pioneer at SRI International, the Silicon Valley research laboratory. “There are more vulnerabilities than ever, more ways to exploit them than ever, and now the government wants to dumb everything down further.”


The authors include Neumann, Harold Abelson, Susan Landau, and Bruce Schneier.

The IT Containers That Went To War

Tue, 07 Jul 2015 15:01:00

1sockchuck writes: Parachuting a container full of IT gear into a war zone is challenging enough. In the mountains of Afghanistan, helicopters had to deliver modular data centers in three minutes or less, lest the choppers be targeted by Taliban rockets. UK vendor Cannon recently spoke with DataCenterDynamics, sharing some of the extreme challenges and lessons learned from deploying portable data centers for military units in deserts and mountains. The same lessons (except, hopefully, with a lower chance of being shot) would apply in lots of other extreme enviroments, too.

Eric Holder Says DoJ Could Strike Deal With Snowden; Current AG Takes Hard Line

Tue, 07 Jul 2015 14:20:00

cold fjord writes with the report at Yahoo that Former Attorney General Eric Holder said today that a "possibility exists" for the Justice Department to cut a deal with ... Edward Snowden that would allow him to return to the United States ... Holder said "we are in a different place as a result of the Snowden disclosures" and that "his actions spurred a necessary debate" that prompted President Obama and Congress to change policies ... "I certainly think there could be a basis for a resolution that everybody could ultimately be satisfied with. I think the possibility exists." A representative of current Attorney General Loretta Lynch, though, said that there has been no change in the government's position ("This is an ongoing case so I am not going to get into specific details but I can say our position regarding bringing Edward Snowden back to the United States to face charges has not changed."), Holder's musings aside. As the article points out, too, "any suggestion of leniency toward Snowden would likely run into strong political opposition in Congress as well as fierce resistance from hard-liners in the intelligence community."
