CVE-2018-4916: Adobe Acrobat Pro DC ImageConversion TIFF Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. The vulnerability is caused by the computation that writes data past the end of the intended buffer; the computation is part of the image conversion module that handless TIFF data. An attacker can potentially leverage the vulnerability to corrupt sensitive data or execute arbitrary code.
Other sources
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 parsing of TIFF images. The issue results from the lack of proper validation of 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 under the context of the current process.
