Summary
The remote host is missing an update to openjdk-6 announced via advisory DSA 2161-2.
Insight
Insight
It was discovered that the floating point parser in OpenJDK, an implementation of the Java platform, can enter an infinite loop when processing certain input strings. Such input strings represent valid numbers and can be contained in data supplied by an attacker over the network, leading to a denial-of-service attack. For the old stable distribution (lenny), this problem has been fixed in version 6b18-1.8.3-2~lenny1. Note that this update introduces an OpenJDK package based on the IcedTea release 1.8.3 into the old stable distribution. This addresses several dozen security vulnerabilities, most of which are only exploitable by malicious mobile code. A notable exception is CVE-2009-3555, the TLS renegotiation vulnerability. This update implements the protocol extension described in RFC 5746, addressing this issue. This update also includes a new version of Hotspot, the Java virtual machine, which increases the default heap size on machines with several GB of RAM. If you run several JVMs on the same machine, you might have to reduce the heap size by specifying a suitable -Xmx argument in the invocation of the java command.
Solution
Solution
We recommend that you upgrade your openjdk-6 packages.
