  "description": "The libseccomp library provides an interface to the Linux Kernel\u0027s 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.\n\nThe following packages have been upgraded to a later upstream version: libseccomp (2.4.1). (BZ#1688938)\n\nSecurity Fix(es):\n\n* libseccomp: incorrect generation of syscall filters in libseccomp (CVE-2019-9893)\n\nFor more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.\n\nAdditional Changes:\n\nFor detailed information on changes in this release, see the Red Hat Enterprise Linux 8.1 Release Notes linked from the References section.",
