critical Nessus Plugin ID 56987

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the openjdk-6 packages.

For the stable distribution (squeeze), this problem has been fixed in version 6b18-1.8.10-0+squeeze2.
