SYNTHESIS OF THE VULNERABILITY
An attacker can force the usage of a freed memory area in Script
Debugging of Internet Explorer, in order to trigger a denial of
service, and possibly to execute code.
Impacted products: IE
Severity: 2/4
Creation date: 03/10/2014
DESCRIPTION OF THE VULNERABILITY
The Internet Explorer product allows developers to enable the
Script Debugging feature.
However, when a ScriptEngine object is manipulated, a freed
pointer is reused.
An attacker can therefore force the usage of a freed memory area
in Script Debugging of Internet Explorer, in order to trigger a
denial of service, and possibly to execute code.
