Vulnerability Spotlight: Remote code execution vulnerabilities in Adobe Acrobat Reader
Summary: Cisco Talos discovered two remote code execution vulnerabilities in Adobe Acrobat Reader, TALOS-2018-0778/CVE-2019-7761 affecting version 2019.10.20069 and TALOS-2019-0796/CVE-2019-7831 affecting version 2019.10.20098, each triggered when a user opens a malicious PDF or visits a malicious web page. Both bugs stem from JavaScript embedded in a PDF that causes heap corruption, which with careful memory manipulation can lead to arbitrary code execution, and Talos worked with Adobe to release an update.
Bottom line: Acrobat is the most widely used PDF reader on the market, so the potential target base for these bugs is fairly large, and the embedded JavaScript that enables interactive forms gives an attacker the ability to precisely control memory layout.
