Adobe tries again to fix Flash vulnerability

Malware authors found a way to continue to exploit a vulnerability patched last month

Adobe released an emergency patch on Tuesday to fix a Flash Player vulnerability that was fixed last month but was quickly exploited again.

The company had issued a patch for the flaw, called CVE-2104-8439, but attackers soon found a way around that fix.

The latest update to Flash adds a "mitigation" for CVE-2104-8439, a vulnerability that could lead to the installation of malware.

The latest version for Windows and Apple's Mac OS is 15.0.0.239, and the latest for Linux is 11.2.202.424. Flash Player for Google's Chrome and Microsoft's Internet Explorer browsers should automatically update, but the update also can be installed manually from Adobe.

CVE-2014-8439 was patched on Oct. 14 along with three other vulnerabilities, but apparently the patch wasn't enough to stop exploit-kit developers from reverse-engineering the fix and finding a way to continue to exploit it.

Exploit kits are malicious software packages that automatically attack computers that browse to a website where one is installed, looking for software vulnerabilities and delivering malware.

Timo Hirvonen, a senior researcher at F-Secure, wrote on Tuesday that the company received an exploit sample from independent security researcher Kaffeine. The exploit appeared to still work despite Adobe's October patches.

"We considered the possibility that maybe the latest patch prevented the exploit from working [but] the root cause of the vulnerability was still unfixed, so we contacted the Adobe Product Security Incident Response Team," Hirvonen wrote. Adobe "confirmed our theory and released an out-of-band update to provide additional hardening."

Kaffeine found the Angler exploit kit was exploiting CVE-2104-8439 again just a week after Adobe's Oct. 14 patch release, with the Astrum and Nuclear exploit kits adding the same capability soon after, Hirvonen wrote.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
