RHEL 2.1 : IBMJava2 (RHSA-2007:0072)

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

IBMJava2-JRE and IBMJava2-SDK packages that correct several security
issues are available for Red Hat Enterprise Linux 2.1.

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

IBM's 1.3.1 Java release includes the IBM Java 2 Runtime Environment
and the IBM Java 2 Software Development Kit.

Vulnerabilities were discovered in the Java Runtime Environment. An
untrusted applet could use these vulnerabilities to access data from
other applets. (CVE-2006-6736, CVE-2006-6737)

Buffer overflow vulnerabilities were discovered in the Java Runtime
Environment. An untrusted applet could use these flaws to elevate its
privileges, possibly reading and writing local files or executing
local applications. (CVE-2006-6731)

Daniel Bleichenbacher discovered an attack on PKCS #1 v1.5 signatures.
Where an RSA key with exponent 3 is used it may be possible for an
attacker to forge a PKCS #1 v1.5 signature that would be incorrectly
verified by implementations that do not check for excess data in the
RSA exponentiation result of the signature. (CVE-2006-4339)

All users of IBMJava2 should upgrade to these updated packages, which
contain IBM's 1.3.1 SR10a Java release which resolves these issues.

Please note that the packages in this erratum are the same as those we
released on January 24th 2007 with advisories RHBA-2007:0023 and
RHEA-2007:0024. We have issued this security update as these previous
advisories did not specify that they fixed critical security issues.
If you have already updated to those versions of IBMJava you will not
need to apply this update.
