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 to elevate its privileges. CVE-2011-3544 The Java scripting engine lacks necessary security manager checks, allowing untrusted Java code to elevate its privileges. CVE-2011-3547 The skip method in java.io.InputStream uses a shared buffer, allowing untrusted Java code 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 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 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.
