Red Hat released version 5.3 of its Enterprise Linux distribution on Tuesday, about eight months after version 5.2. We gave an overview of the new features of the beta version of RHEL 5.3 in November. Now, it’s here. The new version offers enhanced virtualization scalability, OpenJDK functionality and Intel Nehalem processor support.
The company released a risk report comparing RHEL 5.2 to RHEL 5.3. Briefly, the report explains that 61 advisories were released to address the 181 vulnerabilities found in version 5.2. The seven critical advisories were for Firefox, Samba, and OpenSSH. The new version has all the updated security features, and the risk report shows that Red Hat saw fewer vulnerabilities with 5.2 than it did in 5.1 and 5.0.
The author of the risk report, Mark Cox, explains that “for Red Hat Enterprise Linux 5 since release and to date, every critical vulnerability has had an update to address it available from the Red Hat Network either the same day or the next calendar day after the issue was public.”
