RHSA-2007:0818 - Security Advisory

Topic

Updated java-1.5.0-sun packages that correct several security issues are
available for Red Hat Enterprise Linux 4 Extras.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

The Java Runtime Environment (JRE) contains the software and tools
that users need to run applets and applications written using the Java
programming language.

The Javadoc tool was able to generate HTML documentation pages that
contained cross-site scripting (XSS) vulnerabilities. A remote attacker
could use this to inject arbitrary web script or HTML. (CVE-2007-3503)

The Java Web Start URL parsing component contained a buffer overflow
vulnerability within the parsing code for JNLP files. A remote attacker
could create a malicious JNLP file that could trigger this flaw and execute
arbitrary code when opened. (CVE-2007-3655)

The JSSE component did not correctly process SSL/TLS handshake requests. A
remote attacker who is able to connect to a JSSE-based service could
trigger this flaw leading to a denial-of-service. (CVE-2007-3698)

A flaw was found in the applet class loader. An untrusted applet could use
this flaw to circumvent network access restrictions, possibly connecting to
services hosted on the machine that executed the applet. (CVE-2007-3922)

All users of java-sun-1.5.0 should upgrade to these packages, which contain
Sun Java 1.5.0 Update 12 that corrects these issues.
