Vulnerability Spotlight: Adobe Reader DC Parser Confusion

Summary: Cisco Talos disclosed TALOS-2017-0361 / CVE-2017-11263, an arbitrary code execution vulnerability in Adobe Acrobat Reader DC that manifests as parser confusion in the AcroForm parsing functionality. A crafted PDF can push the parser into an unintended state, letting an attacker abuse an unchecked pointer to access or overwrite arbitrary memory in the process, and Adobe has released a software update addressing the flaw.

Bottom line: The exploit path is an emailed malicious PDF, so the delivery mechanism is one your users open by habit, and Talos notes the flaw was identified by its own researcher Aleksandar Nikolic while also publishing Snort rules that it says are subject to change pending additional vulnerability information.
