3. Problem Description

 a. Critical Memory corruption vulnerability

    A memory corruption condition may occur in the virtual machine
    hardware. A malicious request sent from the guest operating
    system to the virtual hardware may cause the virtual hardware to
    write to uncontrolled physical memory.

    VMware would like to thank Andrew Honig of the Department of
    Defense for reporting this issue.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2008-4917 to this issue.

    The following table lists what action remediates the vulnerability
    (column 4) if a solution is available.

 b. Updated Service Console package bzip2

    bzip2 versions before 1.0.5 can crash if certain flaws in compressed
    data lead to reading beyond the end of a buffer.  This might cause
    an application linked to the libbz2 library to crash when
    decompressing malformed archives.

    The Common Vulnerabilities and Exposures project (cve.mitre.org)
    has assigned the name CVE-2008-1372 to this issue.
