CentOS 5 : java-1.6.0-openjdk (CESA-2009:0377)
Critical Nessus Plugin ID 43736
SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated java-1.6.0-openjdk packages that fix several security issues are now available for Red Hat Enterprise Linux 5.
This update has been rated as having important security impact by the Red Hat Security Response Team.
These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit. The Java Runtime Environment (JRE) contains the software and tools that users need to run applications written using the Java programming language.
A flaw was found in the way that the Java Virtual Machine (JVM) handled temporary font files. A malicious applet could use this flaw to use large amounts of disk space, causing a denial of service.
A memory leak flaw was found in LittleCMS (embedded in OpenJDK). An application using color profiles could use excessive amounts of memory, and possibly crash after using all available memory, if used to open specially crafted images. (CVE-2009-0581)
Multiple integer overflow flaws which could lead to heap-based buffer overflows, as well as multiple insufficient input validation flaws, were found in the way LittleCMS handled color profiles. An attacker could use these flaws to create a specially crafted image file which could cause a Java application to crash or, possibly, execute arbitrary code when opened. (CVE-2009-0723, CVE-2009-0733)
A NULL pointer dereference flaw was found in LittleCMS. An application using color profiles could crash while converting a specially crafted image file. (CVE-2009-0793)
A flaw in the Java API for XML Web Services (JAX-WS) service endpoint handling could allow a remote attacker to cause a denial of service on the server application hosting the JAX-WS service endpoint.
A flaw in the way the Java Runtime Environment initialized LDAP connections could allow a remote, authenticated user to cause a denial of service on the LDAP service. (CVE-2009-1093)
A flaw in the Java Runtime Environment LDAP client could allow malicious data from an LDAP server to cause arbitrary code to be loaded and then run on an LDAP client. (CVE-2009-1094)
Several buffer overflow flaws were found in the Java Runtime Environment unpack200 functionality. An untrusted applet could extend its privileges, allowing it to read and write local files, as well as to execute local applications with the privileges of the user running the applet. (CVE-2009-1095, CVE-2009-1096)
A flaw in the Java Runtime Environment Virtual Machine code generation functionality could allow untrusted applets to extend their privileges. An untrusted applet could extend its privileges, allowing it to read and write local files, as well as execute local applications with the privileges of the user running the applet.
A buffer overflow flaw was found in the splash screen processing. A remote attacker could extend privileges to read and write local files, as well as to execute local applications with the privileges of the user running the java process. (CVE-2009-1097)
A buffer overflow flaw was found in how GIF images were processed. A remote attacker could extend privileges to read and write local files, as well as execute local applications with the privileges of the user running the java process. (CVE-2009-1098)
Note: The flaws concerning applets in this advisory, CVE-2009-1095, CVE-2009-1096, and CVE-2009-1102, can only be triggered in java-1.6.0-openjdk by calling the 'appletviewer' application.
All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.
SolutionUpdate the affected java-1.6.0-openjdk packages.
