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+squeeze2. 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.
