Intel Makes Spectre Patch Progress, while Adobe Grapples with Latest Flash Bug

It’s been a busy week in InfoSec land, as Intel released a new Spectre patch, iOS source code was leaked online, and a zero-day Flash bug got exploited in the wild.

Also making noise these past few days: A major security hole in the Grammarly web app, WordPress updates tripping over each other, and a data breach at a Swiss telecom company.

As has been the case these past few weeks, we’ll lead off with the latest on Meltdown and Spectre, the hardware vulnerabilities whose disclosure on Jan. 3 sent shockwaves through the IT industry due to their scope and severity, and which are expected to remain an issue for years.

Update: Patch Tuesday May 2016

Update: Adobe released the patch for Adobe Flash that addresses the current 0-day CVE-2016-4117 in APSB16-15. It also patches another 24 vulnerabilities that are mostly rated critical.

At the moment no patch is available, but a workaround has been published that neutralizes current attacks. We recommend the same thing the attackers are doing: scan your infrastructure for occurrences of ImageMagick and then apply the workaround in the policy.xml file. I did this immediately on my sites, even though I use ImageMagick only in commandline mode for thumbnail creation. BTW, the workaround has become more complete over the last 2 weeks, so it is worth taking another look even if you have applied it already…
