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 Bitmap Handling Use After Free Vulnerability."

Informations

CWE-ID Nom de la faiblesse 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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 est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

EPSS Score

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

EPSS Percentile

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres 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
