Several local and remote vulnerabilities have been discovered in the Linux
kernel that may lead to a denial of service or the execution of arbitrary
code. The Common Vulnerabilities and Exposures project identifies the
following problems:


     A local denial of service vulnerability in do_fork() has been found.     


     A local denial of service vulnerability in proc memory handling has
     been found.


     A buffer overflow in the panic handling code has been found.


     A local denial of service vulnerability through a null pointer
     dereference in the IA64 process handling code has been found.


     A local denial of service vulnerability through an infinite loop in
     the signal handler code has been found.


     An information leak in the context switch code has been found on
     the IA64 architecture.


     Unsafe use of copy_to_user in USB drivers may disclose sensitive


     A race condition in the i386 page fault handler may allow privilege


     Multiple vulnerabilities in the SMB filesystem code may allow denial
     of service of information disclosure.


     An information leak discovered in the SMB filesystem code.


     A local denial of service vulnerability has been found in the SCM layer.


     An integer overflow in the terminal code may allow a local denial of
     service vulnerability.


     A local privilege escalation in the MIPS assembly code has been found.
     A memory leak in the ip_options_get() function may lead to denial of

     Multiple overflows exist in the io_edgeport driver which might be usable
     as a denial of service attack vector.

     Bryan Fulton reported a bounds checking bug in the coda_pioctl function
     which may allow local users to execute arbitrary code or trigger a denial
     of service attack.


     A local privilege escalation in the mremap function has been found


     Inproper initialization of the RTC may disclose information.


     Insufficient input sanitising in the load_elf_binary() function may
     lead to privilege escalation.


     Incorrect error handling in the binfmt_elf loader may lead to privilege


     A buffer overflow in the binfmt_elf loader may lead to privilege
     escalation or denial of service.


     The open_exec function may disclose information.


     The binfmt code is vulnerable to denial of service through malformed
     a.out binaries.


     A denial of service vulnerability in the ELF loader has been found.


     A programming error in the unix_dgram_recvmsg() function may lead to
     privilege escalation.


     The ELF loader is vulnerable to denial of service through malformed


     Crafted ELF binaries may lead to privilege escalation, due to 
     insufficient checking of overlapping memory regions.


     A race condition in the load_elf_library() and binfmt_aout() functions
     may allow privilege escalation.


     An integer overflow in the Moxa driver may lead to privilege escalation.


     A remote denial of service vulnerability has been found in the PPP


     An IA64 specific local denial of service vulnerability has been found
     in the unw_unwind_to_user() function.

The following matrix explains which kernel version for which architecture
fix the problems mentioned above:

                                     Debian 3.0 (woody)
     Source                          2.4.18-14.4
     Alpha architecture              2.4.18-15woody1
     Intel IA-32 architecture        2.4.18-13.2
     HP Precision architecture       62.4 
     PowerPC architecture            2.4.18-1woody6
     PowerPC architecture/XFS        20020329woody1            
     PowerPC architecture/benh       20020304woody1
     Sun Sparc architecture          22woody1    

We recommend that you upgrade your kernel package immediately and reboot
the machine.

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 dist-upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
