Ubuntu Update for Linux kernel vulnerabilities USN-1373-1

Please Install the Updated Packages.

It was discovered that the Java HttpServer class did not limit the number of headers read from a HTTP request. A remote attacker could cause a denial of service by sending special requests that trigger hash collisions predictably. (CVE-2011-5035) ATTENTION: this update changes previous Java HttpServer class behavior by limiting the number of request headers to 200. This may be increased by adjusting the sun.net.httpserver.maxReqHeaders property. It was discovered that the Java Sound component did not properly check buffer boundaries. A remote attacker could use this to cause a denial of service or view confidential data. (CVE-2011-3563) It was discovered that the Java2D implementation does not properly check graphics rendering objects before passing them to the native renderer. A remote attacker could use this to cause a denial of service or to bypass Java sandbox restrictions. (CVE-2012-0497) It was discovered that an off-by-one error exists in the Java ZIP file processing code. An attacker could us this to cause a denial of service through a maliciously crafted ZIP file. (CVE-2012-0501) It was discovered that the Java AWT KeyboardFocusManager did not properly enforce keyboard focus security policy. A remote attacker could use this with an untrusted application or applet to grab keyboard focus and possibly expose confidential data. (CVE-2012-0502) It was discovered that the Java TimeZone class did not properly enforce security policy around setting the default time zone. A remote attacker could use this with an untrusted application or applet to set a new default time zone and bypass Java sandbox restrictions. (CVE-2012-0503) It was discovered the Java ObjectStreamClass did not throw an accurately identifiable exception when a deserialization failure occurred. A remote attacker could use this with an untrusted application or applet to bypass Java sandbox restrictions. (CVE-2012-0505) It was discovered that the Java CORBA implementation did not properly protect repository identifiers on certain CORBA objects. A remote attacker could use this to corrupt object data. (CVE-2012-0506) It was discovered that the Java AtomicReferenceArray class implementation did not properly check if an array was of the expected Object[] type. A remote attacker could use this with a malicious application or applet to bypass Java sandbox restrictions. (CVE-2012-0507)
