Note: release notes of clamav version 1.4.1, 1.4.2 and 1.4.3 are
marked upstream as security maintenance releases. This Buildroot
commit is not marked as security fix because those security patches
were already applied in the v1.0.x series. See version bumps
to v1.0.7 [1], v1.0.8 [2] and v1.0.9 [3].
