CVE-2018-4896
https://notcve.org/view.php?id=CVE-2018-4896
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 module that handles Enhanced Metafile Format Plus (EMF+) data. A successful attack can lead to sensitive data exposure. Se ha descubierto un problema en Adobe Acrobat Reader 2018.009.20050 y anteriores, 2017.011.30070 y anteriores y 2015.006.30394 y anteriores. Esta vulnerabilidad ocurre como resultado de un cálculo que lee datos más allá del final del búfer objetivo; el cálculo forma parte del módulo de conversión de imágenes que gestiona datos Enhanced Metafile Format Plus (EMF+). • http://www.securityfocus.com/bid/102996 http://www.securitytracker.com/id/1040364 https://helpx.adobe.com/security/products/acrobat/apsb18-02.html • CWE-125: Out-of-bounds Read •
