Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : icedtea-web, openjdk-6, openjdk-6b18 vulnerabilities (USN-1263-1) (BEAST)

Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Deepak Bhole discovered a flaw in the Same Origin Policy (SOP)
implementation in the IcedTea web browser plugin. This could allow a
remote attacker to open connections to certain hosts that should not
be permitted. (CVE-2011-3377)

Juliano Rizzo and Thai Duong discovered that the block-wise AES
encryption algorithm block-wise as used in TLS/SSL was vulnerable to a
chosen-plaintext attack. This could allow a remote attacker to view
confidential data. (CVE-2011-3389)

It was discovered that a type confusion flaw existed in the in the
Internet Inter-Orb Protocol (IIOP) deserialization code. A remote
attacker could use this to cause an untrusted application or applet to
execute arbitrary code by deserializing malicious input.
(CVE-2011-3521)

It was discovered that the Java scripting engine did not perform
SecurityManager checks. This could allow a remote attacker to cause an
untrusted application or applet to execute arbitrary code with the
full privileges of the JVM. (CVE-2011-3544)

It was discovered that the InputStream class used a global buffer to
store input bytes skipped. An attacker could possibly use this to gain
access to sensitive information. (CVE-2011-3547)

It was discovered that a vulnerability existed in the AWTKeyStroke
class. A remote attacker could cause an untrusted application or
applet to execute arbitrary code. (CVE-2011-3548)

It was discovered that an integer overflow vulnerability existed in
the TransformHelper class in the Java2D implementation. A remote
attacker could use this cause a denial of service via an application
or applet crash or possibly execute arbitrary code. (CVE-2011-3551)

It was discovered that the default number of available UDP sockets for
applications running under SecurityManager restrictions was set too
high. A remote attacker could use this with a malicious application or
applet exhaust the number of available UDP sockets to cause a denial
of service for other applets or applications running within the same
JVM. (CVE-2011-3552)

It was discovered that Java API for XML Web Services (JAX-WS) could
incorrectly expose a stack trace. A remote attacker could potentially
use this to gain access to sensitive information. (CVE-2011-3553)

It was discovered that the unpacker for pack200 JAR files did not
sufficiently check for errors. An attacker could cause a denial of
service or possibly execute arbitrary code through a specially crafted
pack200 JAR file. (CVE-2011-3554)

It was discovered that the RMI registration implementation did not
properly restrict privileges of remotely executed code. A remote
attacker could use this to execute code with elevated privileges.
(CVE-2011-3556, CVE-2011-3557)

It was discovered that the HotSpot VM could be made to crash, allowing
an attacker to cause a denial of service or possibly leak sensitive
information. (CVE-2011-3558)

It was discovered that the HttpsURLConnection class did not properly
perform SecurityManager checks in certain situations. This could allow
a remote attacker to bypass restrictions on HTTPS connections.
(CVE-2011-3560).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.8
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
