    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 (including applets) to elevate its privileges.
    
    CVE-2011-0864
    	Hotspot, the just-in-time compiler in OpenJDK, mishandled
    	certain byte code instructions, allowing untrusted code
    	(including applets) 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 (including applets) could access information
    	about network interfaces which was not intended to be public.
    	(Note that the interface MAC address is still available to
    	untrusted code.)
    
    CVE-2011-0868
    	A float-to-long conversion could overflow, , allowing
    	untrusted code (including applets) to crash the virtual
    	machine.
    
    CVE-2011-0869
    	Untrusted code (including applets) could intercept HTTP
    	requests by reconfiguring proxy settings through a SOAP
    	connection.
    
    CVE-2011-0871
    	Untrusted code (including applets) 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.
    
    For the oldstable distribution (lenny), these problems will be fixed
    in a separate DSA for technical reasons.
    
    For the stable distribution (squeeze), these problems have been fixed
    in version 6b18-1.8.9-0.1~squeeze1.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid(, these problems have been fixed in version 6b18-1.8.9-0.1.
    
    We recommend that you upgrade your OpenJDK packages.
