Among the critical vulnerabilities, 39 security flaws could allow arbitrary code execution upon exploitation. Whereas 2 critical vulnerabilities could result in information disclosure, and 2 could lead to privilege escalation.

Regarding the 28 important vulnerabilities, all of them were out-of-bounds read bugs resulting in information disclosure.

As described in their security advisory, the vulnerabilities affected the following software versions for Windows and Mac systems.

  • Acrobat DC and Acrobat Reader DC (continuous track) – versions 2019.010.20069 and earlier
