Ubuntu Update for Linux kernel vulnerabilities USN-1263-2
Vulnerability Insight:
USN-1263-1 fixed vulnerabilities in OpenJDK 6. The upstream patch for
the chosen plaintext attack on the block-wise AES encryption algorithm
(CVE-2011-3389) introduced a regression that caused TLS/SSL connections
to fail when using certain algorithms. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
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 ...
