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 occurs due to computation that reads data past the end of the target buffer, specifically within the Unicode mapping module invoked during Enhanced Metafile Format (EMF) data processing for image conversion. This can lead to sensitive data exposure. Additionally, it allows attackers to potentially execute code remotely.

Recommendations For versions 2018.009.20050 and earlier, update to a version later than 2018.009.20050 to resolve the issue. For versions 2017.011.30070 and earlier, update to a version later than 2017.011.30070 to resolve the issue. For 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 processing of Enhanced Metafile Format (EMF) data to minimize the risk of exploitation.
