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
