SecurityTracker URL:  http://securitytracker.com/id/1022789
CVE Reference:   CVE-2009-2671, CVE-2009-2672, CVE-2009-2673   (Links to External Site)
Date:  Aug 28 2009
Impact:   Disclosure of user information, Host/resource access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): JDK and JRE 6 Update 14 and prior, JDK and JRE 5.0 Update 19 and prior
Description:   A vulnerability was reported in the Java Runtime Environment (JRE) proxy mechanism. A remote user can obtain potentially sensitive. A remote user can initiate socket or URL connections.

A remote user can create a specially crafted applet or Web Start application that, when loaded by the target user, will exploit one of several flaws in the JRE SOCKS implementation.

A remote user can obtain the username of the user running the applet or application.

A remote user can obtain browser cookies, which may lead to session hijacking.

A remote user can open socket or URL connections from the applet or application to arbitrary hosts.

Gregory Fleischer reported some of these vulnerabilities.

Impact:   A remote user can obtain the username of the user running the applet or application.

A remote user can obtain browser cookies, which may lead to session hijacking.

A remote user can connect to arbitrary ports on arbitrary hosts.

1. Summary:

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

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 Extras - i386, ppc, s390, s390x, x86_64
Red Hat Desktop version 4 Extras - i386, x86_64
Red Hat Enterprise Linux ES version 4 Extras - i386, x86_64
Red Hat Enterprise Linux WS version 4 Extras - i386, x86_64
RHEL Desktop Supplementary (v. 5 client) - i386, x86_64
RHEL Supplementary (v. 5 server) - i386, ppc, s390x, x86_64

3. Description:

The IBM 1.5.0 Java release includes the IBM Java 2 Runtime Environment and
the IBM Java 2 Software Development Kit.

This update fixes several vulnerabilities in the IBM Java 2 Runtime
Environment and the IBM Java 2 Software Development Kit. These
vulnerabilities are summarized on the IBM "Security alerts" page listed in
the References section. (CVE-2009-2625, CVE-2009-2670, CVE-2009-2671,
CVE-2009-2672, CVE-2009-2673, CVE-2009-2675)

All users of java-1.5.0-ibm are advised to upgrade to these updated
packages, containing the IBM 1.5.0 SR10 Java release. All running instances
of IBM Java must be restarted for this update to take effect.

Note: The packages included in this update are identical to the packages
made available by RHEA-2009:1208 and RHEA-2009:1210 on the 13th of
August 2009. These packages are being reissued as a Red Hat Security
Advisory as they fixed a number of security issues that were not made
public until after those errata were released. Since the packages are
identical, there is no need to install this update if RHEA-2009:1208 or
RHEA-2009:1210 has already been installed.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network.  Details on how to use
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
