Synopsis

Moderate: java-1.4.2-bea security update

Type/Severity

Security Advisory: Moderate

Topic

Updated java-1.4.2-bea packages that correct several security issues and
add enhancements are now available for Red Hat Enterprise Linux 4 Extras.

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

Description

The BEA WebLogic JRockit 1.4.2_15 JRE and SDK contain BEA WebLogic JRockit
Virtual Machine 1.4.2_15 and are certified for the Java 2 Platform,
Standard Edition, v1.4.2.

A buffer overflow in the Java Runtime Environment image handling code was
found. If an attacker is able to cause a server application to process a
specially crafted image file, it may be possible to execute arbitrary code
as the user running the Java Virtual Machine. (CVE-2007-2788,
CVE-2007-2789, CVE-2007-3004)

A denial of service flaw was discovered in the Java Applet Viewer. An
untrusted Java applet could cause the Java Virtual Machine to become
unresponsive. Please note that the BEA WebLogic JRockit 1.4.2_15 does not
ship with a browser plug-in and therefore this issue could only be
triggered by a user running the "appletviewer" application. (CVE-2007-3005)

A denial of service flaw was found in the way the JSSE component processed
SSL/TLS handshake requests. A remote attacker able to connect to a JSSE
enabled service could send a specially crafted handshake which would cause
the Java Runtime Environment to stop responding to future requests.
(CVE-2007-3698)

A flaw was found in the way the Java Runtime Environment processes font
data. An applet viewed via the "appletviewer" application could elevate
its privileges, allowing the applet to perform actions with the same
permissions as the user running the "appletviewer" application. It may also
be possible to crash a server application which processes untrusted font
information from a third party. (CVE-2007-4381)

All users of java-1.4.2-bea should upgrade to these updated packages, which
contain the BEA WebLogic JRockit 1.4.2_15 release that resolves these
issues.
