    Package        : kernel-image-2.4.16-lart, kernel-image-2.4.16-netwinder,  kernel-image-2.4.16-riscpc, kernel-patch-2.4.16-arm
    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 PowerPC/Apus kernel 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) this problem has been fixed in
    version 2.4.26/20040204 of lart, netwinder and riscpc image and in
    version 20040204 of kernel-patch-2.4.16-arm.
    
    Other architectures will probably mentioned in a separate advisory or
    are not affected (m68k).
    
    For the unstable distribution (sid) these problems will be fixed soon.
    
    We recommend that you upgrade your Linux kernel packages immediately.

    Package        : kernel-patch-2.4.17-mips
    Vulnerability  : missing function return value check
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : 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.
    
    For the stable distribution (woody) this problem has been fixed in
    version 2.4.17-0.020226.2.woody5 for mips and mipsel kernel images.
    
    Other architectures will probably mentioned in a separate advisory or
    are not affected (m68k).
    
    For the unstable distribution (sid) this problem will be fixed soon
    with the next upload of a 2.4.19 kernel image and in version
    2.4.22-0.030928.3 for 2.4.22 for the mips and mipsel architectures.
    
    This problem is also fixed in the upstream version of Linux 2.4.25 and
    2.6.3.
    
    We recommend that you upgrade your Linux kernel packages immediately.
