Description The issue is a heap overflow vulnerability triggered by crafted TIFF data within an XPS file, causing an out of bounds memory access. This can potentially allow an attacker to corrupt sensitive data or execute arbitrary code. The vulnerability is related to the parsing of the TIFF directory count in XPS files.

Recommendations For Adobe Acrobat Reader versions 2018.009.20050 and earlier, update to a version later than 2018.009.20050 to resolve the issue. For Adobe Acrobat Reader versions 2017.011.30070 and earlier, update to a version later than 2017.011.30070 to resolve the issue. For Adobe Acrobat Reader versions 2015.006.30394 and earlier, update to a version later than 2015.006.30394 to resolve the issue. As a temporary workaround, consider avoiding the use of crafted TIFF data within XPS files to minimize the risk of exploitation.
