Internet Explorer 9/10 Recycler::ProcessMark Information Disclosure

Date Disclosed:

Date Patched:
Patch Not Yet Available


Affected Software:
Internet Explorer 9 and 10

Internet Explorer 9 and 10 contain an information disclosure vulnerability that may allow a remote attacker to gain access to sensitive information, such as memory addresses and memory contents. This vulnerability is caused by the mark and sweep algorithm within the JavaScript component in Internet Explorer, which incorrectly does not mark some objects, allowing them to persist in memory.


Code Execution:

Information Disclosure
This vulnerability may be used by attackers to reveal memory addresses and other useful information to help supplement an exploit targeting another vulnerability. Because this vulnerability discloses sensitive memory information, an attacker may use this to bypass defensive measures, such as ASLR.

Avoid using Internet Explorer 9 and 10 when possible. 

 BeyondTrust's Retina® Network Security Scanner scans devices to detect for this vulnerability.
