Pending analysis
Type:
CWE-416 Use After Free

Description

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. This vulnerability is an instance of a use after free vulnerability. The vulnerability is triggered by a crafted PDF file that can cause a memory access violation exception in the XFA engine because of a dangling reference left as a consequence of freeing an object in the computation that manipulates internal nodes in a graph representation of a document object model used in XFA. Successful exploitation could lead to arbitrary code execution.
