The vulnerabilities of PDF viewing and editing programs such as Adobe Acrobat Document Cloud, Adobe Acrobat Reader Document Cloud, Adobe Acrobat 2017, Adobe Acrobat Reader 2017, and Adobe Acrobat 2020 are related to an operation that allows data to be written beyond the buffer in memory. This allows attackers to gain unauthorized access to protected information.
