    Package        : kernel-image-2.4.17-hppa
    Vulnerability  : several vulnerabilities
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CAN-2003-0961 CAN-2003-0985 CAN-2004-0077
    
    Several local root exploits have been discovered recently in the Linux
    kernel.  This security advisory updates the mips kernel 2.4.19 for
    Debian GNU/Linux.  The Common Vulnerabilities and Exposures project
    identifies the following problems that are fixed with this update:
    
    CAN-2003-0961:
    
       An integer overflow in brk() system call (do_brk() function) for
       Linux allows a local attacker to gain root privileges.  Fixed
       upstream in Linux 2.4.23.
    
    CAN-2003-0985:
    
       Paul Starzetz discovered a flaw in bounds checking in mremap() in
       the Linux kernel (present in version 2.4.x and 2.6.x) which may
       allow a local attacker to gain root privileges.  Version 2.2 is not
       affected by this bug.  Fixed upstream in Linux 2.4.24.
    
    CAN-2004-0077:
    
       Paul Starzetz and Wojciech Purczynski of isec.pl discovered a
       critical security vulnerability in the memory management code of
       Linux inside the mremap(2) system call.  Due to missing function
       return value check of internal functions a local attacker can gain
       root privileges.  Fixed upstream in Linux 2.4.25 and 2.6.3.
    
    For the stable distribution (woody) these problems have been fixed in
    version 32.3 of kernel-image-2.4.17-hppa.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 2.4.25-1 of kernel-image-2.4.25-hppa.
    
    We recommend that you upgrade your Linux kernel packages immediately.
    
    
    Upgrade Instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.

      These files will probably be moved into the stable distribution on
      its next revision.

    Several local root exploits have been discovered recently in the Linux
    kernel.  This security advisory updates the PA-RISC kernel 2.4.18 for
    Debian GNU/Linux.  The Common Vulnerabilities and Exposures project
    identifies the following problems that are fixed with this update:

       return value check of internal functions a local attacker can gain
       root privileges.  Fixed upstream in Linux 2.4.25 and 2.6.3.
    
    Please note that the source package has to include a lot of updates in
    order to compile the package, which wasn't possible with the old
    source package.
    
    For the stable distribution (woody) these problems have been fixed in
    version 62.1 of kernel-image-2.4.18-hppa.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 2.4.25-1 of kernel-image-2.4.25-hppa.
    
    We recommend that you upgrade your Linux kernel packages immediately.
