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 that reads data past the end of the target buffer, specifically within the image conversion engine when processing Enhanced Metafile Format (EMF) data that embeds an image in the bitmap (BMP) file format. This can lead to sensitive data exposure. Additionally, it is described as an out-of-bounds read vulnerability that allows 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 processing of EMF data that embeds BMP images until a patch is available.
