    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.

    libseccomp (2.4.1). (BZ#1688938)
    
    Security Fix(es):
    
    * libseccomp: incorrect generation of syscall filters in libseccomp
    (CVE-2019-9893)
