Synopsis
The remote Debian host is missing a security-related update.
Description
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 or 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-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 fixes the problems mentioned above :
Debian 3.0 (woody) Source 2.4.16-1woody2 arm/lart 20040419woody1 arm/netwinder 20040419woody1 arm/riscpc 20040419woody1
Solution
Upgrade the kernel package immediately and reboot the machine.
