RedHat: Critical: IBMJava2 security update
Summary
Summary
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.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
