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.     

CVE-2005-0489

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

CVE-2004-0394

 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                          2.4.19-4
 Sun Sparc architecture          26woody1
 Little endian MIPS architecture 0.020911.1.woody5

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

Upgrade Instructions
