Microsoft Internet Explorer 6 Memory Address Disclosure
Patch Not Yet Available
Internet Explorer 6
Formerly Internet Explorer 7 and 8
Microsoft Internet Explorer 6 contains a vulnerability when calculating timer ID's that could cause specific memory addresses (i.e. persistent memory locations) to be disclosed. If an attacker is able to combine knowledge of memory locations with a more critical vulnerability (e.g. one that could potentially allow code execution), then it could be further leveraged to bypass ASLR (Address Space Layout Randomization) protection.
Remote disclosure of information
This client-side vulnerability could allow an attacker to gain information about persistent memory addresses, which could be used alongside other exploits to compromise a system. By itself, the vulnerability is not very potent, but when combined with other vulnerabilities, it could have a much higher impact.
