Unspecified vulnerability in Microsoft Internet Explorer 8 on Windows 7 allows remote attackers to execute arbitrary code via unknown vectors triggered by clicking on a link, as demonstrated by Nils during a PWN2OWN competition at CanSecWest 2009.

Unspecified vulnerability in Internet Explorer 8 on Microsoft Windows 7 allows remote attackers to execute arbitrary code via unknown vectors, possibly related to a use-after-free issue, as demonstrated by Peter Vreugdenhil during a Pwn2Own competition at CanSecWest 2010.

Use-after-free vulnerability in Microsoft Internet Explorer 6 through 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to the CMarkup::IsConnectedToPrimaryMarkup function, as exploited in the wild in April 2014. NOTE: this issue originally emphasized VGX.DLL, but Microsoft clarified that "VGX.DLL does not contain the vulnerable code leveraged in this exploit. Disabling VGX.DLL is an exploit-specific workaround that provides an immediate, effective workaround to help block known attacks."
