Description The issue occurs due to computation that reads data past the end of the target buffer, which is part of the XPS font processing. This can lead to sensitive data exposure. A successful attack can also allow attackers to execute code remotely.

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 restricting the use of XPS font processing until a patch is available.
