    Package : openjdk-6
    Vulnerability : several
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2010-4476 CVE-2009-3555
    Debian Bug : 612660

    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.

    We recommend that you upgrade your openjdk-6 packages.
