Four vulnerabilities were identified in Internet Explorer, each of which could allow a remote attacker to execute arbitrary code on an affected system.
Microsoft has released a cumulative security update for Internet Explorer (IE) following the identification of four vulnerabilities. Two of the vulnerabilities were caused when IE attempts to access an uninitialized or a deleted object, which results in memory corruption. Causes for the other vulnerabilities are memory corruption that resulted from accessing a corrupted virtual function table, and improper calculation of an object's size during a copy operation.
Each of the vulnerability could allow an attacker to execute code on a compromised system in the context of the current user. To address this issue, necessary modification has been made in the way that IE handles objects in memory. Users are highly recommended to install the latest security update as a protection against potential exploit attempts.
