Adobe has released security updates that patch tens of vulnerabilities in the company’s Acrobat, Reader, Flash Player and Creative Cloud Desktop Application products.

Adobe has addressed a dozen critical vulnerabilities affecting the Windows, Mac, Linux and Chrome OS versions of Flash Player. The list of flaws includes a security bypass vulnerability and various memory issues that could lead to arbitrary code execution.

Independent researchers and experts from Tencent, CloverSec Labs, COSIG and Palo Alto Networks have been credited for reporting the Flash Player vulnerabilities, which have been assigned a priority rating of “1.”

The company has fixed a total of 71 critical vulnerabilities in Adobe Acrobat and Reader, although these have been rated as having level “2” priority, which makes them less likely to be exploited.

A large majority of the flaws patched in Acrobat and Reader are use-after-free, heap buffer overflow, integer overflow and other memory corruption issues that could be exploited for arbitrary code execution. The latest updates also address a security bypass and various methods that can be used to bypass JavaScript API execution restrictions.

Adobe has credited researchers from Palo Alto Networks, Fortinet, the Nanyang Technological University, FireEye, ZDI, Clarified Security and Source Incite for reporting these flaws. Some of the issues were brought to the company’s attention by independent experts and one or more individuals who wanted to remain anonymous.

Adobe also released a security update for its Creative Cloud Desktop Application for Windows. The update fixes an unquoted search path vulnerability (CVE-2016-6935) that could lead to local privilege escalation.

The company said there was no evidence that any of the vulnerabilities patched with these updates had been exploited in the wild.
