Title: Adobe issues security updates for Acrobat Reader

Description: Adobe recently disclosed multiple vulnerabilities in its Acrobat PDF Reader, including for both desktop and Android versions. Among them are a heap buffer overflow and use-after-free vulnerability that Cisco Talos researchers discovered. Acrobat reader integrates into web browsers as a plugin for rendering PDFs. As such, tricking a user into visiting a malicious web page or sending a specially crafted email attachment can be enough to trigger these vulnerabilities. There is also a bug that's considered "important" in all Android versions of Acrobat that could allow an adversary to disclose sensitive information on an affected device.
