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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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: https://code.google.com/p/google-security-research/issues/detail?id=293 Platform: Win7 32-bit. trigger.cpp should fire the issue, with two caveats: - PoC will NOT work if compiled as a debug build. - PoC will trigger the condition every time but the subsequent corruption might not cause a crash every time. It may be necessary to run the PoC multiple times. debug.txt is a sample crash log. Analysis from Nils: --- Using the series of calls we are able to free the bitmap object, a reference to this object still exists in the trigger process after killing the first notepad process. At this time we are able to replace the freed object in memory. We are not able to reuse this object through the original handle, however another free is triggered when quitting the trigger process, which will decrement the reference counter on the freed or replaced object, either modifying heap metadata or freeing the object which was allocated in the place of the original bitmap object. --- Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/38275.zip

Source: https://code.google.com/p/google-security-research/issues/detail?id=311 Bitmap object Use-after-Free #2 The attached PoC triggers a blue screen due to a use after free vulnerability. The crashes are unreliable, however you can use Special Pool in order to get reliable crashes. The crashes indicate that it is possible to write to arbitrary addresses. --- please find the PoC and brief analysis for the issue attached. The analysis mentions how Special Pool can be used to get very reliable crashes, it should crash without Special Pool after a while as well. -- Proof of Concept: https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/38265.zip
