3. Description:
These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit.
A flaw was found in the Java RMI (Remote Method Invocation) registry
implementation. A remote RMI client could use this flaw to execute
arbitrary code on the RMI server running the registry. (CVE-2011-3556)
A flaw was found in the Java RMI registry implementation. A remote RMI
client could use this flaw to execute code on the RMI server with
unrestricted privileges. (CVE-2011-3557)
A flaw was found in the IIOP (Internet Inter-Orb Protocol) deserialization
code. An untrusted Java application or applet running in a sandbox could
use this flaw to bypass sandbox restrictions by deserializing
specially-crafted input. (CVE-2011-3521)
It was found that the Java ScriptingEngine did not properly restrict the
privileges of sandboxed applications. An untrusted Java application or
applet running in a sandbox could use this flaw to bypass sandbox
restrictions. (CVE-2011-3544)
A flaw was found in the AWTKeyStroke implementation. An untrusted Java
application or applet running in a sandbox could use this flaw to bypass
sandbox restrictions. (CVE-2011-3548)
An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the Java2D code used to perform transformations of graphic shapes
and images. An untrusted Java application or applet running in a sandbox
could use this flaw to bypass sandbox restrictions. (CVE-2011-3551)
An insufficient error checking flaw was found in the unpacker for JAR files
in pack200 format. A specially-crafted JAR file could use this flaw to
crash the Java Virtual Machine (JVM) or, possibly, execute arbitrary code
with JVM privileges. (CVE-2011-3554)
It was found that HttpsURLConnection did not perform SecurityManager checks
in the setSSLSocketFactory method. An untrusted Java application or applet
running in a sandbox could use this flaw to bypass connection restrictions
defined in the policy. (CVE-2011-3560)
A flaw was found in the way the SSL 3 and TLS 1.0 protocols used block
ciphers in cipher-block chaining (CBC) mode. An attacker able to perform a
chosen plain text attack against a connection mixing trusted and untrusted
data could use this flaw to recover portions of the trusted data sent over
the connection. (CVE-2011-3389)
Note: This update mitigates the CVE-2011-3389 issue by splitting the first
application data record byte to a separate SSL/TLS protocol record. This
mitigation may cause compatibility issues with some SSL/TLS implementations
and can be disabled using the jsse.enableCBCProtection boolean property.
This can be done on the command line by appending the flag
"-Djsse.enableCBCProtection=false" to the java command.
An information leak flaw was found in the InputStream.skip implementation.
An untrusted Java application or applet could possibly use this flaw to
obtain bytes skipped by other threads. (CVE-2011-3547)
A flaw was found in the Java HotSpot virtual machine. An untrusted Java
application or applet could use this flaw to disclose portions of the VM
memory, or cause it to crash. (CVE-2011-3558)
The Java API for XML Web Services (JAX-WS) implementation in OpenJDK was
configured to include the stack trace in error messages sent to clients. A
remote client could possibly use this flaw to obtain sensitive information.
(CVE-2011-3553)
It was found that Java applications running with SecurityManager
restrictions were allowed to use too many UDP sockets by default. If
multiple instances of a malicious application were started at the same
time, they could exhaust all available UDP sockets on the system.
(CVE-2011-3552)
This erratum also upgrades the OpenJDK package to IcedTea6 1.9.10. Refer to
the NEWS file, linked to in the References, for further information.
All users of java-1.6.0-openjdk are advised to upgrade to these updated
packages, which resolve these issues. All running instances of OpenJDK Java
must be restarted for the update to take effect.
