      Linux Orinoco Drivers Information Leakage
    ------------------------------------------------------------------------

    SUMMARY

    The <http://sourceforge.net/projects/orinoco> Linux Orinoco driver,
    included in the kernel since 2.4.3 and in David Hinds' pcmcia-cs package
    since 3.1.30 supports a large number of wireless NICs based on the
    Lucent/Agere Hermes, Symbol Spectrum24 and Intersil/Conexant Prism 2/2.5/3
    chipsets.

    Vulnerability in Orinoco Drivers allows Information Leakage.

    DETAILS

    Due to padding of Ethernet frames with uninitialized data, it is possible
    to remotely obtain parts of memory which may contain sensitive
    information.

    Following sample dumps illustrate the problem:

    Attacker can use arping(8) to send ARP requests to the target running
    vulnerable orinoco drivers and observe contents of uninitialized memory in
    the ARP replies.
