- More information:
Integer overflow errors in the JPEG and font parser allow untrusted code (including applets) to elevate its privileges.
Hotspot, the just-in-time compiler in OpenJDK, mishandled certain byte code instructions, allowing untrusted code (including applets) to crash the virtual machine.
A race condition in signed object deserialization could allow untrusted code to modify signed content, apparently leaving its signature intact.
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.)
A float-to-long conversion could overflow, allowing untrusted code (including applets) to crash the virtual machine.
Untrusted code (including applets) could intercept HTTP requests by reconfiguring proxy settings through a SOAP connection.
Untrusted code (including applets) could elevate its privileges through the Swing MediaTracker code.
The TLS implementation does not guard properly against certain chosen-plaintext attacks when block ciphers are used in CBC mode.
The CORBA implementation contains a deserialization vulnerability in the IIOP implementation, allowing untrusted Java code (such as applets) to elevate its privileges.
The Java scripting engine lacks necessary security manager checks, allowing untrusted Java code (such as applets) to elevate its privileges.
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.
The java.awt.AWTKeyStroke class contains a flaw which allows untrusted Java code (such as applets) to elevate its privileges.
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.
Malicous Java code can use up an excessive amount of UDP ports, leading to a denial of service.
JAX-WS enables stack traces for certain server responses by default, potentially leaking sensitive information.
JAR files in pack200 format are not properly checked for errors, potentially leading to arbitrary code execution when unpacking crafted pack200 files.
The RMI Registry server lacks access restrictions on certain methods, allowing a remote client to execute arbitary code.
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.
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 oldstable distribution (lenny), these problems have been fixed in version 6b18-1.8.10-0~lenny2.
We recommend that you upgrade your openjdk-6 packages.
