Vulnerability Spotlight: Information leak vulnerability in Adobe Acrobat Reader
Summary: Cisco Talos discovered an information leak vulnerability in Adobe Acrobat Reader DC version 2019.021.20048 that exists in the way the software processes embedded JavaScript in PDFs. An attacker triggers it by getting a victim to open a crafted PDF, likely via an email attachment or a web page, and with careful memory manipulation it can disclose sensitive information that could be used to bypass mitigations when exploiting another vulnerability.
What you should know: The leak is not the payload on its own: disclosed memory can be used to bypass mitigations for a second exploit, so a single malicious PDF opened from an email attachment or web page can weaken the defenses that would otherwise stop a follow-on attack.
