Descriptions du CVE

demux/mkv/mkv.hpp in the MKV demuxer plugin in VideoLAN VLC media player 1.1.6.1 and earlier allows remote attackers to cause a denial of service (crash) and execute arbitrary commands via a crafted MKV (WebM or Matroska) file that triggers memory corruption, related to "class mismatching" and the MKV_IS_ID macro.

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.
