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 occurs as a result of computation that reads data that is past the end of the target buffer; the computation is part of the XPS module that handles TIFF data. A successful attack can lead to sensitive data exposure.

This vulnerability is an instance of a heap overflow vulnerability in the image conversion engine, when handling JPEG data embedded within an XPS file. A successful attack can lead to code corruption, control-flow hijack, or an information leak attack.

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.

This vulnerability occurs as a result of computation that reads data that is past the end of the target buffer; the computation is part of the Unicode mapping module that is invoked when processing Enhanced Metafile Format (EMF) data (during image conversion). A successful attack can lead to sensitive data exposure.

This vulnerability occurs as a result of computation that reads data that is past the end of the target buffer; the computation occurs in the image conversion engine when processing Enhanced Metafile Format (EMF) data related to handling of bitmap rectangles. A successful attack can lead to sensitive data exposure.
