Vulnerability Spotlight: Multiple Java Script vulnerabilities in Adobe Acrobat Reader
Summary: Cisco Talos discovered a heap buffer overflow (CVE-2020-24435) and a use-after-free (CVE-2020-24437) in Adobe Acrobat Reader DC, both triggered by specific JavaScript embedded in a PDF and reachable by opening a malicious file or visiting a malicious web page. Talos also reproduced a previously patched heap buffer overflow, TALOS-2020-1031, in a newer version of the reader, and confirmed version 2020.012.20043 is affected by the use-after-free.
What's compelling: Both flaws can lead to arbitrary code execution through a PDF opened in what is often the default reader on the system, and one previously patched overflow was found reproducible again in a newer build - so a patch that shipped once is not proof the fix held.
