RHSA-2008:0156 - Security Advisory

Topic

Updated java-1.5.0-bea packages that correct several security issues are
now available for Red Hat Enterprise Linux 4 Extras and 5 Supplementary.

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

Description

The BEA WebLogic JRockit 1.5.0_14 JRE and SDK contain BEA WebLogic JRockit
Virtual Machine 1.5.0_14 and are certified for the Java 5 Platform,
Standard Edition, v1.5.0.

A flaw in the applet caching mechanism of the Java Runtime Environment
(JRE) did not correctly process the creation of network connections. A
remote attacker could use this flaw to create connections to services on
machines other than the one that the applet was downloaded from.
(CVE-2007-5232)

Untrusted Java Applets were able to drag and drop a file to a Desktop
Application. A user-assisted remote attacker could use this flaw to move or
copy arbitrary files. (CVE-2007-5239)

The Java Runtime Environment (JRE) allowed untrusted Java Applets or
applications to display oversized windows. This could be used by remote
attackers to hide security warning banners. (CVE-2007-5240)

Unsigned Java Applets communicating via a HTTP proxy could allow a remote
attacker to violate the Java security model. A cached, malicious Applet
could create network connections to services on other machines. (CVE-2007-5273)

Two vulnerabilities in the Java Runtime Environment allowed an untrusted
application or applet to elevate the assigned privileges. This could be
misused by a malicious website to read and write local files or execute
local applications in the context of the user running the Java process.
(CVE-2008-0657)

Those vulnerabilities concerned with applets can only be triggered in
java-1.5.0-bea by calling the 'appletviewer' application.

All users of java-1.5.0-bea should upgrade to these updated packages, which
contain the BEA WebLogic JRockit 1.5.0_14 release that resolves these issues.
