Notifications for a CVE
Stay informed of any changes for a specific CVE.
CVE Descriptions
The access permissions for a UNIX domain socket are ignored in Solaris 2.x and SunOS 4.x, and other BSD-based operating systems before 4.4, which could allow local users to connect to the socket and possibly disrupt or control the operations of the program using that socket.

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.

Solaris 2.6 and many other unices/clones have a serious problem with their unix domain socket implementation that has it's origins in old BSD code. Any unix socket created by any application is set mode 4777. In Solaris versions 2.5 and earlier, the permissions were ignored completely. The applications are vulnerable to being connected to and written to by anyone. This could lead to a whole number of application-specific security compromises.
Here is some sample code (by Nirva):
#include <stdio.h>
#include <stdlib.h>
#include <sys/un.h>
#include <sys/socket.h>
main(int argc, char *argv[])
{
struct sockaddr_un addr;
int s;
s = socket(AF_UNIX, SOCK_STREAM, 0);
bzero(&addr, sizeof(addr));
addr.sun_family = AF_UNIX;
strcpy(addr.sun_path, "/tmp/yoursocket");
if (bind(s, (struct sockaddr *)&addr, sizeof(addr)) < 0) {
perror("bind");
exit(1);
}
sleep(100);
exit(0);
}
