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

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.

The following matrix explains which kernel version for which architecture fix the problems mentioned above:
Debian 3.1 (sarge) Source 2.4.17-1woody4 HP Precision architecture 32.5 Intel IA-64 architecture 011226.18 IBM S/390 architecture/image 2.4.17-2.woody.5 IBM S/390 architecture/patch 0.0.20020816-0.woody.4 PowerPC architecture (apus) 2.4.17-6 MIPS architecture 2.4.17-0.020226.2.woody7
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.
