RHSA-2008:0245 - Security Advisory

Topic

Updated java-1.6.0-bea packages that correct several security issues are
now available for Red Hat Enterprise Linux 5 Supplementary.

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

Description

The BEA WebLogic JRockit 1.6.0_03 JRE and SDK contain BEA WebLogic JRockit
Virtual Machine 1.6.0_03, and are certified for the Java 6 Platform,
Standard Edition, v1.6.0.

The Java XML parsing code processed external entity references even when
the "external general entities" property was set to "FALSE". This allowed
remote attackers to conduct XML External Entity (XXE) attacks, possibly
causing a denial of service, or gaining access to restricted resources.
(CVE-2008-0628)

A flaw was found in the Java XSLT processing classes. An untrusted
application or applet could cause a denial of service, or execute arbitrary
code with the permissions of the user running the JRE. (CVE-2008-1187)

A flaw was found in the JRE image parsing libraries. An untrusted
application or applet could cause a denial of service, or possible execute
arbitrary code with the permissions of the user running the JRE.
(CVE-2008-1193)

A flaw was found in the JRE color management library. An untrusted
application or applet could trigger a denial of service (JVM crash).
(CVE-2008-1194)

The vulnerabilities concerning applets listed above can only be triggered
in java-1.6.0-bea, by calling the "appletviewer" application.

Users of java-1.6.0-bea are advised to upgrade to these updated packages,
which resolve these issues.
