CVE Descriptions

Use-after-free vulnerability in the kernel-mode drivers in Microsoft Windows Server 2003 SP2 and R2 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows local users to gain privileges via a crafted application, aka "Microsoft Windows Kernel Object Use After Free Vulnerability."

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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.

EDB Verified : Yes

Source: https://code.google.com/p/google-security-research/issues/detail?id=304 Creating a device context with the flag (DCX_NORESETATTRS) and selecting a brush object into the device context will result in the brush being freed on process exit without the reference to the object being cleared. The PoC consists of two files (prime304.cpp and poc304.cpp). poc304 will execute prime304, which triggers the issue and allows poc304 to retrieve a handle to the device context with the pointer to the freed object. We can confirm this by requesting the handle for the brush object from the device context, resulting in reading freed memory. In some cases the issue leads to memory corruption when for example another object is allocated into the space of the free brush object (see attached crash logs for examples).
