Glossary 75
Errata
Information published by Red Hat describing security fixes, bug fixes, and package enhance-
ments for Red Hat Linux. The information includes the topics of the Errata, Bugzilla bug IDs,
relevant releases/architectures, solutions including required RPMs, and MD5 checksums for ver-
ification. Errata are also available at http://www.redhat.com/errata/. Each RHN Errata Alert is
based on the Red Hat Linux Errata List.
Security issues and bug fixes are submitted by Red Hat engineers as well as the Linux community
through Bugzilla which generates a bug report for each issue. Red Hat engineering evaluates the
reports, resolves the bug, and generates new RPM packages. After the Red Hat quality assurance
team tests new packages they are placed on the Red Hat Public File Server and on the Red Hat
Network Server and an Errata is generated.
Errata Alert

systems within an organization. There are three types of Errata Alerts: Security Alerts, Bug Fix
Alerts, and Enhancement Alerts.
