Ubuntu Security Notice (C) 2012-2014 Canonical, Inc. / NASL script (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN 1373-1 fixed vulnerabilities in OpenJDK 6 in Ubuntu 10.04 LTS,
Ubuntu 10.10 and Ubuntu 11.04 for all architectures except for ARM
(armel). This provides the corresponding OpenJDK 6 update for use with
the ARM (armel) architecture in Ubuntu 10.04 LTS, Ubuntu 10.10 and
Ubuntu 11.04.

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).

Solution :

Update the affected packages.
