(RHSA-2007:0829) Critical: java-1.5.0-ibm security update

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

A security vulnerability in the Java Web Start component was discovered. An
untrusted application could elevate it’s privileges, allowing it to read
and write local files that are accessible to the user running the Java Web
Start application. (CVE-2007-2435)

A buffer overflow in the Java Runtime Environment image handling code was
found. An untrusted applet or application could use this flaw to elevate
its privileges and potentially execute arbitrary code as the user running
the java virtual machine. (CVE-2007-2788, CVE-2007-2789, CVE-2007-3004)

An unspecified vulnerability was discovered in the Java Runtime
Environment. An untrusted applet or application could cause the java
virtual machine to become unresponsive. (CVE-2007-3005)

The Javadoc tool was able to generate HTML documentation pages that
contained cross-site scripting (XSS) vulnerabilities. A remote attacker
could use this to inject arbitrary web script or HTML. (CVE-2007-3503)

The Java Web Start URL parsing component contains a buffer overflow
vulnerability within the parsing code for JNLP files. A remote attacker
could create a malicious JNLP file that could trigger this flaw and execute
arbitrary code when opened. (CVE-2007-3655)

A flaw was found in the applet class loader. An untrusted applet could use
this flaw to circumvent network access restrictions, possibly connecting
to services hosted on the machine that executed the applet. (CVE-2007-3922)

All users of java-ibm-1.5.0 should upgrade to these updated packages, which
contain IBM’s 1.5.0 SR5a Java release that resolves these issues.
