(RHSA-2019:3624) Moderate: libseccomp security, bug fix, and enhancement update

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). (BZ#1688938)

Security Fix(es):

• libseccomp: incorrect generation of syscall filters in libseccomp (CVE-2019-9893)
