Adobe Patches Major Security Flaws in PDF Reader, Photoshop

Adobe’s product security response machine revved into high gear this week with the release of multiple patches for gaping security holes in widely deployed software products.

According to the San Jose, Calif. software maker, this month’s batch of patches address a swathe of potentially dangerous vulnerabilities in Adobe Acrobat and Reader, Adobe Photoshop, and the ever-present Adobe Creative Cloud Desktop Application.

The most serious of the vulnerabilities could allow attackers to take complete control of a Windows or macOS machine with minimal user action.  In some cases, malicious exploits can be triggered remotely to hijack unpatched machines, Adobe warned.

Windows and MacOS users and network administrators are encouraged to prioritize the Adobe Acrobat and Reader update, a patch that provides cover for at least five memory corruption vulnerabilities that expose users to remote code execution attacks.

“These updates address multiple critical vulnerabilities. Successful exploitation could lead to arbitrary code execution in the context of the current user,” Adobe said.

The company issued a separate bulletin to document a pair of potentially dangerous buffer overflow flaws in Adobe Photoshop that expose both Windows and macOS users to code execution attacks.

The Adobe Patch Tuesday rollout for June also covers security problems in Adobe Connect, Adobe Experience Manager, and Adobe Robohelp Server.
