Microsoft Internet Explorer Peer Objects Use-After-Free RCE
CVE-2010-0806 is a use-after-free vulnerability in the Peer Objects component of Microsoft Internet Explorer (iepeers.dll) affecting Internet Explorer 6, 6 SP1, and 7. The flaw occurs when Internet Explorer accesses an invalid pointer after an object has been deleted, resulting in memory corruption. Microsoft and downstream reporting describe this as an 'Uninitialized Memory Corruption Vulnerability,' but the supplied technical description identifies the core bug class as a use-after-free in iepeers.dll. A remote attacker can trigger the condition by getting a victim to load a specially crafted web page containing malicious HTML and script content. Successful exploitation can corrupt process memory and execute attacker-controlled code in the context of the logged-in user. The vulnerability was exploited in the wild in March 2010 and was later used as a zero-day in targeted attacks, including activity attributed to GREF.
