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:


 CVE-2004-0427

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

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

 CVE-2004-0447

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

 CVE-2004-0554

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

 CVE-2004-0565

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

 CVE-2004-0685

     Unsafe use of copy_to_user in USB drivers may disclose sensitive
     information.

 CVE-2005-0001

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

 CVE-2004-0883

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

 CVE-2004-0949

     An information leak discovered in the SMB filesystem code.

 CVE-2004-1016

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

 CVE-2004-1333

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

 CVE-2004-0997

     A local privilege escalation in the MIPS assembly code has been found.
 
 CVE-2004-1335
 
     A memory leak in the ip_options_get() function may lead to denial of
     service.
      
 CVE-2004-1017

     Multiple overflows exist in the io_edgeport driver which might be usable
     as a denial of service attack vector.
 
 CVE-2005-0124

     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.

 CVE-2005-0528

     A local privilege escalation in the mremap function has been found

 CVE-2003-0984

     Inproper initialization of the RTC may disclose information.

 CVE-2004-1070

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

 CVE-2004-1071

     Incorrect error handling in the binfmt_elf loader may lead to privilege
     escalation.

 CVE-2004-1072

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

 CVE-2004-1073

     The open_exec function may disclose information.

 CVE-2004-1074

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

 CVE-2004-0138

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

 CVE-2004-1068

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

 CVE-2004-1234

     The ELF loader is vulnerable to denial of service through malformed
     binaries.

 CVE-2005-0003

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

 CVE-2004-1235

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

 CVE-2005-0504

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

 CVE-2005-0384

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

 CVE-2005-0135

     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                          2.4.16-1woody2
     arm/lart                        20040419woody1
     arm/netwinder                   20040419woody1
     arm/riscpc                      20040419woody1

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.
