Descriptions
Use-after-free vulnerability in the CMshtmlEd::Exec function in mshtml.dll in Microsoft Internet Explorer 6 through 9 allows remote attackers to execute arbitrary code via a crafted web site, as exploited in the wild in September 2012.
Vulnerabilidad de error en la gestión de recursos en la función CMshtmlEd::Exec en mshtml.dll en Microsoft Internet Explorer 6 a 9 permite a atacantes remotos ejecutar código arbitrario a través de un sitio web diseñado, como se ha explotado en septiembre de 2012.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. 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 CCommand::Exec function. It is possible to free certain objects in a callback function called from the CCommand::Exec function. Upon return from this function a local variable is being re-used without check. This can lead to a use-after-free issue that can result in remote code execution under the context of the current process.
Microsoft Internet Explorer contains a use-after-free vulnerability that allows remote attackers to execute code via a crafted web site.
