Summary: An update for libseccomp is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat CodeReady Linux Builder (v. 8) - aarch64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, ppc64le, s390x, x86_64 3. Description: The libseccomp library provides an interface to the Linux Kernel's syscall filtering mechanism, seccomp. The libseccomp API allows an application to specify which system calls or system call arguments the application is allowed to execute, all of which are then enforced by the Linux Kernel. The following packages have been upgraded to a later upstream version: libseccomp (2.4.1).
