Several vulnerabilities have been discovered in OpenJDK, an implementation of the Java SE platform. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2011-0862 Integer overflow errors in the JPEG and font parser allow untrusted code to elevate its privileges. CVE-2011-0864 Hotspot, the just-in-time compiler in OpenJDK, mishandled certain byte code instructions, allowing untrusted code to crash the virtual machine. CVE-2011-0865 A race condition in signed object deserialization could allow untrusted code to modify signed content, apparently leaving its signature intact. CVE-2011-0867 Untrusted code could access information about network interfaces which was not intended to be public. CVE-2011-0868 A float-to-long conversion could overflow, , allowing untrusted code to crash the virtual machine. CVE-2011-0869 Untrusted code could intercept HTTP requests by reconfiguring proxy settings through a SOAP connection. CVE-2011-0871 Untrusted code could elevate its privileges through the Swing MediaTracker code. In addition, this update removes support for the Zero/Shark and Cacao Hotspot variants from the i386 and amd64 due to stability issues. These Hotspot variants are included in the openjdk-6-jre-zero and icedtea-6-jre-cacao packages, and these packages must be removed during this update.
