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
