Do you know what does RHSA, RHEA and RHBA stands for in RedHat Errata ?
RHEA = Red Hat Enhancement Advisory, these can ONLY contain enhancement fixes (e.g. new features).
RHBA = Red Hat Bug Advisory, these contain bug fixes, and can optionally also contain enhancements, essentially bugs outrank enhancements for reporting purposes.
RHSA = Red Hat Security Advisory, these contain security fixes, and can optionally also contain bugs and/or enhancements, essentially security issues outrank bugs/enhancements for reporting purposes.
The identifying "name" of an RHEA/RHBA/RHSA is the advisory type, the year, identifying number (simply sequential starting at 1) and a version (in case they ever get an update), e.g. "RHSA-2015:2594-1".
I've added an authoritative knowledge base article "Explanation of RHSA, RHBA, and RHEA advisories" that answers:
- What are RHSA, RHBA, and RHEA advisories?
- What happens if an RHEA or an RHBA is found to have fixed a security flaw?
- How does advisory numbering work?
