CVE-2015-7829

Adobe Reader y Acrobat 10.x en versiones anteriores a 10.1.16 y 11.x en versiones anteriores a 11.0.13, Acrobat y Acrobat Reader DC Classic en versiones anteriores a 2015.006.30094 y Acrobat y Acrobat Reader DC Continuous en versiones anteriores a 2015.009.20069 en Windows no maneja correctamente las uniones en el directorio Synchronizer, lo que permite a atacantes borrar archivos arbitrarios a través de Adobe Collaboration Sync, un caso relacionado con CVE-2015-2428.

This vulnerability allows local attackers to delete arbitrary files on vulnerable installations of Adobe Reader. 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 handling of junction points. An attacker running code in the context of a sandboxed Adobe Reader process can set up a junction point in the Synchronizer folder and then run Adobe Collaboration Sync which will delete the contents of the folder. An attacker can leverage this vulnerability to delete files as a normal user from a sandboxed process.
