Updated Versions:

rPath Issue Tracking System:


    Previous versions of the kernel have a weakness which in a non-default
    configuration (if vm.mmap_min_addr is 0) allows normal users processes
    to execute arbitrary code as the root user.  rPath Linux is configured
    by default with vm.mmap_min_addr=65536 and so is not vulnerable
    by default.  Furthermore, rPath Linux does not include two other
    mechanisms by which this vulnerability has been exploited (pulseaudio
    and SELinux policy permitting access to address 0).
    In addition, the open-vm-tools package (including kernel modules)
    has been updated to the most recent upstream release for continued
    compatibility with new VMware hosts.  In addition, this enables user
    programs to use the libraries included in open-vm-tools.  However,
    the library interfaces included in open-vm-tools are not being
    maintained by rPath as a stable library interface; future updates of
    the open-vm-tools package will follow whatever changes have been made
    in the upstream open-vm-tools package to the open-vm-tools libraries,
    even if those changes are incompatible with the current versions.
