Description

The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmap_match_any (called indirectly from cil_check_neverallow). This occurs because there is sometimes a lack of checks for invalid statements in an optional block.

Solution(s)

  • alma-upgrade-libsepol
  • alma-upgrade-libsepol-devel
  • alma-upgrade-libsepol-static
