Name of the Vulnerable Software and Affected Versions Adobe Acrobat Reader versions 2018.009.20050 and earlier Adobe Acrobat Reader versions 2017.011.30070 and earlier Adobe Acrobat Reader versions 2015.006.30394 and earlier

Description The issue arises from a computation in the image conversion engine that handles Enhanced Metafile Format (EMF), which reads data past the end of the target buffer. This can lead to sensitive data exposure. A successful attack may allow remote code execution.

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 disabling the image conversion engine that handles EMF until a patch is available.
