Las versiones de Adobe Acrobat Reader 11.0.19 y anteriores, 15.006.30280 y anteriores, 15.023.20070 y anteriores tienen una vulnerabilidad de fuga de dirección de memoria en el módulo weblink.

This vulnerability allows a remote attacker to disclose sensitive information on vulnerable installations of Adobe Reader DC. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the Weblink plugin. The process does not properly validate user-supplied data which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code under the context of the current process.
