Debian DSA-2358-1 : openjdk-6 - several vulnerabilities (BEAST)

critical Nessus Plugin ID 57499


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


Several vulnerabilities have been discovered in OpenJDK, an implementation of the Java platform. This combines the two previous openjdk-6 advisories, DSA-2311-1 and DSA-2356-1.

- CVE-2011-0862 Integer overflow errors in the JPEG and font parser allow untrusted code (including applets) to elevate its privileges.

- CVE-2011-0864 Hotspot, the just-in-time compiler in OpenJDK, mishandled certain byte code instructions, allowing untrusted code (including applets) to crash the virtual machine.

- CVE-2011-0865 A race condition in signed object deserialization could allow untrusted code to modify signed content, apparently leaving its signature intact.

- CVE-2011-0867 Untrusted code (including applets) could access information about network interfaces which was not intended to be public. (Note that the interface MAC address is still available to untrusted code.)

- CVE-2011-0868 A float-to-long conversion could overflow, allowing untrusted code (including applets) to crash the virtual machine.

- CVE-2011-0869 Untrusted code (including applets) could intercept HTTP requests by reconfiguring proxy settings through a SOAP connection.

- CVE-2011-0871 Untrusted code (including applets) could elevate its privileges through the Swing MediaTracker code.

- 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 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 class does not perform proper security manager checks in the setSSLSocketFactory() method, allowing untrusted Java code to bypass security policy restrictions.


Upgrade the openjdk-6 packages.

For the oldstable distribution (lenny), these problems have been fixed in version 6b18-1.8.10-0~lenny2.
