NVD Description

Note: Versions mentioned in the description apply only to the upstream libsepol-devel package and not the libsepol-devel package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

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.
