Package : openjdk-6
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2011-3389 CVE-2011-3521 CVE-2011-3544 CVE-2011-3547 CVE-2011-3548 CVE-2011-3551 CVE-2011-3552 CVE-2011-3553 CVE-2011-3554 CVE-2011-3556 CVE-2011-3557 CVE-2011-3560
Several vulnerabilities have been discovered in OpenJDK, an
implementation of the Java platform:
CVE-2011-3389
The TLS implementation does not guard properly against certain
chosen-plaintext attacks when block ciphers are used in CBC
mode.
CVE-2011-3521
The CORBA implementation contains a deserialization
vulnerability in the IIOP implementation, allowing untrusted
Java code (such as applets) to elevate its privileges.
CVE-2011-3544
The Java scripting engine lacks necessary security manager
checks, allowing untrusted Java code (such as applets) to
elevate its privileges.
CVE-2011-3547
The skip() method in java.io.InputStream uses a shared buffer,
allowing untrusted Java code (such as applets) to access data
that is skipped by other code.
CVE-2011-3548
The java.awt.AWTKeyStroke class contains a flaw which allows
untrusted Java code (such as applets) to elevate its
privileges.
CVE-2011-3551
The Java2D C code contains an integer overflow which results
in a heap-based buffer overflow, potentially allowing
untrusted Java code (such as applets) to elevate its
privileges.
CVE-2011-3552
Malicous Java code can use up an excessive amount of UDP
ports, leading to a denial of service.
CVE-2011-3553
JAX-WS enables stack traces for certain server responses by
default, potentially leaking sensitive information.
CVE-2011-3554
JAR files in pack200 format are not properly checked for
errors, potentially leading to arbitrary code execution when
unpacking crafted pack200 files.
CVE-2011-3556
The RMI Registry server lacks access restrictions on certain
methods, allowing a remote client to execute arbitary code.
CVE-2011-3557
The RMI Registry server fails to properly restrict privileges
of untrusted Java code, allowing RMI clients to elevate their
privileges on the RMI Registry server.
CVE-2011-3560
The com.sun.net.ssl.HttpsURLConnection class does not perform
proper security manager checks in the setSSLSocketFactory()
method, allowing untrusted Java code to bypass security policy
restrictions.
For the stable distribution (squeeze), this problem has been fixed in
version 6b18-1.8.10-0+squeeze1.
For the testing distribution (wheezy) and the unstable distribution
(sid), this problem has been fixed in version 6b23~pre11-1.
We recommend that you upgrade your openjdk-6 packages.
