DSA-332-1 linux-kernel-2.4.17 -- several vulnerabilities

Related Vulnerabilities: CVE-2002-0429   CVE-2003-0001   CVE-2003-0127   CVE-2003-0244   CVE-2003-0246   CVE-2003-0247   CVE-2003-0248   CVE-2003-0364  

A number of vulnerabilities have been discovered in the Linux kernel. CVE-2002-0429: The iBCS routines in arch/i386/kernel/traps.c for Linux kernels 2.4.18 and earlier on x86 systems allow local users to kill arbitrary processes via a binary compatibility interface (lcall) CAN-2003-0001: Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets CAN-2003-0127: The kernel module loader allows local users to gain root privileges by using ptrace to attach to a child process that is spawned by the kernel CAN-2003-0244: The route cache implementation in Linux 2.4, and the Netfilter IP conntrack module, allows remote attackers to cause a denial of service (CPU consumption) via packets with forged source addresses that cause a large number of hash table collisions related to the PREROUTING chain CAN-2003-0246: The ioperm system call in Linux kernel 2.4.20 and earlier does not properly restrict privileges, which allows local users to gain read or write access to certain I/O ports. CAN-2003-0247: vulnerability in the TTY layer of the Linux kernel 2.4 allows attackers to cause a denial of service ("kernel oops") CAN-2003-0248: The mxcsr code in Linux kernel 2.4 allows attackers to modify CPU state registers via a malformed address. CAN-2003-0364: The TCP/IP fragment reassembly handling in the Linux kernel 2.4 allows remote attackers to cause a denial of service (CPU consumption) via certain packets that cause a large number of hash table collisions This advisory provides corrected source code for Linux 2.4.17, and corrected binary kernel images for the mips and mipsel architectures. Other versions and architectures will be covered by separate advisories. For the stable distribution (woody), these problems have been fixed in kernel-source-2.4.17 version 2.4.17-1woody1 and kernel-patch-2.4.17-mips version 2.4.17-0.020226.2.woody2. For the unstable distribution (sid) these problems are fixed in kernel-source-2.4.20 version 2.4.20-8. We recommend that you update your kernel packages. NOTE: A system reboot will be required immediately after the upgrade in order to replace the running kernel. Remember to read carefully and follow the instructions given during the kernel upgrade process.

More information:

A number of vulnerabilities have been discovered in the Linux kernel.

  • CVE-2002-0429: The iBCS routines in arch/i386/kernel/traps.c for Linux kernels 2.4.18 and earlier on x86 systems allow local users to kill arbitrary processes via a binary compatibility interface (lcall)
  • CAN-2003-0001: Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets
  • CAN-2003-0127: The kernel module loader allows local users to gain root privileges by using ptrace to attach to a child process that is spawned by the kernel
  • CAN-2003-0244: The route cache implementation in Linux 2.4, and the Netfilter IP conntrack module, allows remote attackers to cause a denial of service (CPU consumption) via packets with forged source addresses that cause a large number of hash table collisions related to the PREROUTING chain
  • CAN-2003-0246: The ioperm system call in Linux kernel 2.4.20 and earlier does not properly restrict privileges, which allows local users to gain read or write access to certain I/O ports.
