   An update that solves one vulnerability and has two fixes
   is now available.

Description:

   This update for libseccomp fixes the following issues:

   Security issues fixed:

   - CVE-2019-9893: An incorrect generation of syscall filters in libseccomp
     was fixed (bsc#1128828)

   libseccomp was updated to new upstream release 2.4.1:

   - Fix a BPF generation bug where the optimizer mistakenly identified
     duplicate BPF code blocks.

   libseccomp was updated to 2.4.0 (bsc#1128828 CVE-2019-9893):

   - Update the syscall table for Linux v5.0-rc5
   - Added support for the SCMP_ACT_KILL_PROCESS action
   - Added support for the SCMP_ACT_LOG action and SCMP_FLTATR_CTL_LOG
     attribute
   - Added explicit 32-bit (SCMP_AX_32(...)) and 64-bit (SCMP_AX_64(...))
     argument comparison macros to help protect against unexpected sign
     extension
   - Added support for the parisc and parisc64 architectures
   - Added the ability to query and set the libseccomp API level via
     seccomp_api_get(3) and seccomp_api_set(3)
   - Return -EDOM on an endian mismatch when adding an architecture to a
     filter
   - Renumber the pseudo syscall number for subpage_prot() so it no longer
     conflicts with spu_run()
   - Fix PFC generation when a syscall is prioritized, but no rule exists
   - Numerous fixes to the seccomp-bpf filter generation code
   - Switch our internal hashing function to jhash/Lookup3 to MurmurHash3
   - Numerous tests added to the included test suite, coverage now at ~92%
   - Update our Travis CI configuration to use Ubuntu 16.04
   - Numerous documentation fixes and updates

   libseccomp was updated to release 2.3.3:

   - Updated the syscall table for Linux v4.15-rc7
