Informations du CVE

Faiblesses connexes

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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

Score EPSS

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.

Percentile EPSS

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: http://blog.skylined.nl/20161207001.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 ZDI did do a more thorough analysis and provide some details in their advisory. I have included a number of reports created using a predecessor of Bug­Id below.
