CVE Descriptions

Use-after-free vulnerability in Microsoft Internet Explorer 9 allows remote attackers to execute arbitrary code via a crafted web site that triggers access to a deleted object, aka "Internet Explorer Use After Free Vulnerability," a different vulnerability than CVE-2013-1313.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name Source
CWE-416 Use After Free
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

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.

<!-- Source: http://blog.skylined.nl/20161208001.html Synopsis A specially crafted web-page can trigger a memory corruption vulnerability in Microsoft Internet Explorer 9. I did not investigate this vulnerability thoroughly, so I cannot speculate on the potential impact or exploitability. Known affected software and attack vectors Microsoft Internet Explorer 9 An attacker would need to get a target user to open a specially crafted web-page. Java­Script does not appear to be required for an attacker to triggering the vulnerable code path. Details This bug was found back when I had very little knowledge and tools to do analysis on use-after-free bugs, so I have no details to share. The EIP provided me with some details of their analysis, which I'll paraphrase here: It is a use-after-free vulnerability where the span object in the frame.html file is reused after being freed. It appears to be impossible to reallocate the freed memory before it is reused. Part of the freed memory is overwritten when it is freed because a WORD Free­Entry­Offset value is stored at offset 0. This value is then used as part of a pointer to a vftable in order to call a method. This pointer now consist of the upper 16-bits of the old vftable and the lower 16-bits contain the Free­Entry­Offset value. Exploitation is near impossible without a way to have more control over this pointer in the freed memory block. ZDI also did a more thorough analysis and provide very similar details in their advisory. I have included a number of reports created using a predecessor of Bug­Id below.
