- CAN-2004-1068: Missing serialization in unix_dgram_recvmsg() could lead to elevated privileges, making it possible for a local attacker to gain root access. Thanks to Paul Starzetz for pointing out this problem.
- CAN-2004-1016: Missing integer overflow checks in sendmsg / control message handling allows a local attacker to crash or halt the machine. This was independent found by Paul Starzetz and Georgi Guninski, and fixed by Herbert Xu.
- A memory leak in the IP option handling in the sendmsg() system call that was reported by Georgi Guninski.
- CAN-2004-1137: Some of the pointer handling in the Linux IGMP code was broken and could allow a local attacker to crash the machine. This was found by Paul Starzetz and fixed by Chris Wright.
- A race condition in SCSI I/O accounting which could lead to erroneous reports on SCSI disk I/O was fixed.
- A memory leak in addition / removal of SCSI target devices was fixed.
- The "memfrac" and "lower_zone_reserve" kernel parameters had no effect since they were used before kernel commandline parsing.
First find out which kernel package to install by using the following command:
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
-
rpm -Fvh k_deflt-*.rpm
for the default kernel image, or -
rpm -Fvh k_itanium2-smp-*.rpm
for the Itanium2 SMP kernel image, or -
rpm -Fhv k_itanium2.rpm-*.rpm
for the Itanium2 kernel image, or rpm -Fhv k_smp-*.rpm
for the SMP kernel image
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
