Adobe has published their monthly Patch Tuesday updates for the month of April 2019. These updates fix various security vulnerabilities in Adobe Flash Player, Shockwave Player, Dreamweaver, Adobe XD CC, Adobe Experience Manager Forms, and Adobe Bridge CC. Vulnerabilities fixed by these updates include arbitrary code execution, information disclosure, remote code execution and sensitive information disclosure. Remote code execution vulnerabilities are particularly dangerous as it could allow attackers to remotely execute commands on your computer, which gives them almost full control to do anything they want.
