PLATFORM: Red Hat Enterprise Linux AS, ES, WS (v. 2.1) DAMAGE: Execute arbitrary code and elevation of privilege. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is MEDIUM. An untrusted applet or application could ASSESSMENT: use this flaw to elevate its privileges and potentially execute arbitrary code as the user running the java virtual machine. ______________________________________________________________________________ CVSS 2 BASE SCORE: 7.5 TEMPORAL SCORE: 5.9 VECTOR: (AV:N/AC:L/Au:N/C:P/I:P/A:P/E:POC/RL:OF/RC:C) ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/s-327.shtml ORIGINAL BULLETIN: https://rhn.redhat.com/errata/RHSA-2008-0133.html CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CVE-2007-3004 CVE-2007-3005 CVE-2007-3922 ______________________________________________________________________________ [***** Start Red Hat RHSA-2008:0133-6 *****] Moderate: IBMJava2 security update Advisory: RHSA-2008:0133-6 Type: Security Advisory Severity: Moderate Issued on: 2008-06-24 Last updated on: 2008-06-24 Affected Products: Red Hat Enterprise Linux AS (v. 2.1) Red Hat Enterprise Linux ES (v. 2.1) Red Hat Enterprise Linux WS (v. 2.1) OVAL: N/A CVEs (cve.mitre.org): CVE-2007-3004 CVE-2007-3005 CVE-2007-3922 Details IBMJava2-JRE and IBMJava2-SDK packages that correct several security issues are available for Red Hat Enterprise Linux 2.1. IBM's 1.3.1 Java release includes the IBM Java 2 Runtime Environment and the IBM Java 2 Software Development Kit. A buffer overflow was found in the Java Runtime Environment image-handling code. 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-2007-3004) 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) 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) These updated packages also add the following enhancements: * Time zone information has been updated to the latest available information, 2007h. * Accessibility support in AWT can now be disabled through a system property, java.assistive. To support this change, permission to read this property must be added to /opt/IBMJava2-131/jre/lib/security/java.policy. Users of IBMJava2 who have modified this file should add this following line to the grant section: permission java.util.PropertyPermission "java.assistive", "read"; All users of IBMJava2 should upgrade to these updated packages, which contain IBM's 1.3.1 SR11 Java release, which resolves these issues. 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.
