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 occurs in the image conversion engine when processing Enhanced Metafile Format (EMF) data related to handling of bitmap rectangles. A successful attack can lead to sensitive data exposure.

Stack-based buffer overflow in a certain ActiveX control in GLChat.ocx 2.5.1.32 in GlobalLink 2.7.0.8, as used in Ourgame GLWorld and possibly other products, allows remote attackers to execute arbitrary code via a long first argument to the ConnectAndEnterRoom method, possibly involving the GLCHAT.GLChatCtrl.1 control, as originally exploited in the wild in October 2007. NOTE: some of these details are obtained from third party information. NOTE: this was originally reported as a heap-based issue by some sources.
