Problem description

This kernel fixes several security vulnerabilities:
  • CAN-2003-0244: The route cache implementation in Linux 2.4 and the Netfilter IP conntrack module allow 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.
  • Fix for several potential buffer overflows in the 32 bit emulation layer.
  • CAN-2003-0247: Fix for local DOS via /dev/console & TIOCCONS.
  • Fix for potential buffer overflow in module load in iCom modem driver.
  • Fix for ptrace kmod patch to restore old behaviour.
Additional following critical bugs were fixed:
  • RAID 1 module is no longer miscompiled.
  • avoid race window in submit_bh.
  • added ethtool eeprom config ioctls.
  • better handling for scsi recovered errors.
  • kmalloc sizeof struct instead of sizeof pointer
  • NFS: Fixed race between mount and lockd.
  • Use different uname -r to avoid module load problems.
  • The ibmsis driver was updated to version 1.18.16, fixing a problem with a 2757 SCSI storage driver.
