CVE Descriptions

Use-after-free vulnerability in the Peer Objects component (aka iepeers.dll) in Microsoft Internet Explorer 6, 6 SP1, and 7 allows remote attackers to execute arbitrary code via vectors involving access to an invalid pointer after the deletion of an object, as exploited in the wild in March 2010, aka "Uninitialized Memory Corruption Vulnerability."

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

This bug was discovered being used in-the-wild and was previously known as the "iepeers" vulnerability. The name comes from Microsoft's suggested workaround to block access to the iepeers.dll file. According to Nico Waisman, "The bug itself is when trying to persist an object using the setAttribute, which end up calling VariantChangeTypeEx with both the source and the destination being the same variant. So if you send as a variant an IDISPATCH the algorithm will try to do a VariantClear of the destination before using it. This will end up on a call to PlainRelease which deref the reference and clean the object."
