The VBScript engine in Microsoft Internet Explorer 6 through 11, and VBScript 5.6 through 5.8, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "VBScript Memory Corruption Vulnerability."

Multiple integer overflows in the Microsoft (1) JScript 5.6 through 5.8 and (2) VBScript 5.6 through 5.8 scripting engines allow remote attackers to execute arbitrary code via a crafted web page, aka "Scripting Memory Reallocation Vulnerability."

Integer overflow in Microsoft Internet Explorer 8 and 9, JScript 5.8, and VBScript 5.8 on 64-bit platforms allows remote attackers to execute arbitrary code by leveraging an incorrect size calculation during object copying, aka "JavaScript Integer Overflow Remote Code Execution Vulnerability."
