Oracle Java Runtime NTLM Authentication Information Leakage Vulnerability
ZDI-11-082: February 15th, 2011
CVE ID
CVE-2010-4466
CVSS Score
6.4, (AV:N/AC:L/Au:N/C:P/I:P/A:N)
Affected Vendors
Oracle
Affected Products
Java Runtime
TippingPoint IPS Customer Protection
TippingPoint IPS customers are protected against this vulnerability by Digital
Vaccine protection filter ID 9709. For further product information on the
TippingPoint IPS:
http://www.tippingpoint.com
Vulnerability Details
This vulnerability allows remote attackers to leak authentication details on
vulnerable installations of the Oracle Java Runtime. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page.
The specific flaw exists in the handling of NTLM authentication requested
generated in the context of the Java Runtime. The Java Virtual Machine will
ignore browser policies and respond to WWW-Authenticate requests from the
Internet zone resulting in the leakage of NTLM authentication hashes to
attackers.
Vendor Response
Oracle has issued an update to correct this vulnerability. More details can be

Oracle Java Applet Clipboard Injection Remote Code Execution Vulnerability
ZDI-11-083: February 15th, 2011
CVE ID
CVE-2010-4465

TippingPoint IPS Customer Protection
TippingPoint IPS customers are protected against this vulnerability by Digital
Vaccine protection filter ID 10851. For further product information on the
TippingPoint IPS:
http://www.tippingpoint.com
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Oracle Java Runtime. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page.
The specific flaw is due to insufficient defenses against system clipboard
hijacking. When in focus, a handle to the system clipboard can be retrieved
without user interaction by a malicious component. The clipboard can then be
arbitrarily read from or written to. By writing a TransferableProxy object to
the system clipboard and then forcing a paste action, arbitrary code can be
executed under the context of the user invoking the JRE.

Oracle Java Unsigned Applet Applet2ClassLoader Remote Code Execution
Vulnerability
ZDI-11-084: February 15th, 2011
CVE ID
CVE-2010-4452
CVSS Score

TippingPoint IPS Customer Protection
TippingPoint IPS customers are protected against this vulnerability by Digital
Vaccine protection filter ID 10594. For further product information on the
TippingPoint IPS:
http://www.tippingpoint.com
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Java Runtime Environment. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.
The specific flaw exists within the findClass method of the
sun.plugin2.applet.Applet2ClassLoader class. Due to a failure to properly
validate URLs supplied by an implicitly trusted applet, it is possible to
execute arbitrary code on Windows 32-bit and 64-bit, as well as Linux 32-bit
platforms under the context of the SYSTEM user.

Oracle Java XGetSamplePtrFromSnd Remote Code Execution Vulnerability
ZDI-11-085: February 15th, 2011

TippingPoint IPS Customer Protection
TippingPoint IPS customers are protected against this vulnerability by Digital
Vaccine protection filter ID 10626. For further product information on the
TippingPoint IPS:
http://www.tippingpoint.com
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle Java. User interaction is required to exploit
this vulnerability in that the target must visit a malicious page or open a
malicious file.
The flaw exists within jsound!XGetSamplePtrFromSnd. When extracting a sample
from a soundbank stream user supplied data is used to calculate the bounds of a
call to PV_Swap16BitSamples. By supplying a specially crafted sound file, a
remote attacker can exploit this vulnerability to execute arbitrary code under
the context of the process.

Oracle Java Webstart Trusted JNLP Extension Remote Code Execution Vulnerability
ZDI-11-086: February 15th, 2011

TippingPoint IPS Customer Protection
TippingPoint IPS customers are protected against this vulnerability by Digital
Vaccine protection filter ID 10619. For further product information on the
TippingPoint IPS:
http://www.tippingpoint.com
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle's Java Runtime Environment. User interaction
is required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.
The specific flaw exists within the Java Webstart loader of the Java Runtime
Environment. When parsing a .jnlp file containing an extension, the loader will
honor the permissions defined within. This will allow one to explicitly define
the security permissions of their java component which will then get executed.
This will allow one to execute code outside of the context of the JRE sandbox.
Vendor Response
Oracle has issued an update to correct this vulnerability. More details can be
