Multiple vulnerabilities have been discovered in Microsoft's web browser, Internet Explorer. These vulnerabilities could allow remote code execution or an elevation of privilege if a user views a specially crafted webpage in Internet Explorer. An attacker who successfully exploits this vulnerability could gain the same user rights as the current user. Depending on the privileges associated with the user, an attacker could install programs; view, change, or delete data; or create new accounts with full user rights.
- Internet Explorer 11
- Internet Explorer 10
- Internet Explorer 9
- Internet Explorer 8
- Internet Explorer 7
- Internet Explorer 6
Multiple vulnerabilities were discovered in Internet Explorer due to the way objects in memory are improperly accessed. The vulnerabilities are as follows:
- Nine Memory Corruption Vulnerabilities
- One ASLR Bypass Vulnerability
These vulnerabilities could allow an attacker to execute remote code by luring a victim to a malicious website. When the website is visited, the attacker's script will run with same permissions as the affected user account. Successful exploitation of these vulnerabilities could result in an attacker gaining elevated privileges on the system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
We recommend the following actions be taken:
- Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
- Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
