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 2.4.18-14.4
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.


Debian GNU/Linux 3.0 alias woody
- --------------------------------


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