Adobe Acrobat Pro DC ASCII85Decode Heap-based Buffer Overflow Remote Code Execution Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Acrobat Pro 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 processing of PostScript files. When parsing ASCII85Decode data, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
