RHSA-2008:0100 - Security Advisory

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 3 Extras,
Red Hat Enterprise Linux 4 Extras, and 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 1.4.2_16 JRE and SDK contains BEA WebLogic JRockit
Virtual Machine 1.4.2_16 and is 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 could induce a server application to process a
specially crafted image file, the attacker could potentially cause a
denial-of-service or execute arbitrary code as the user running the Java
Virtual Machine. (CVE-2007-2788, CVE-2007-2789)

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 processed 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. The same
flaw could, potentially, crash a server application which processed
untrusted font information from a third party. (CVE-2007-4381)

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 files 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 over-sized 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)

Please note: the vulnerabilities noted above concerned with applets can
only be triggered in java-1.4.2-bea by calling the "appletviewer"
application.

All users of java-1.4.2-bea should upgrade to these updated packages, which
contain the BEA WebLogic JRockit 1.4.2_16 release which resolves these
issues.
