CVE-2018-4884: Adobe Acrobat Pro DC ImageConversion EMF BMP Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
An issue was discovered in Adobe Acrobat Reader 2018.009.20050 and earlier versions, 2017.011.30070 and earlier versions, 2015.006.30394 and earlier versions. This vulnerability occurs as a result of computation that reads data that is past the end of the target buffer; the computation is part of the image conversion engine when processing Enhanced Metafile Format (EMF) data that embeds an image in the bitmap (BMP) file format. A successful attack can lead to sensitive data exposure.
Other sources
This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Adobe Acrobat Pro DC. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of BMP images embedded inside EMF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
