- CVE-2006-2271: The ECNE chunk handling in Linux SCTP allowed remote attackers to cause a denial of service (kernel panic) via an unexpected chunk when the session is in CLOSED state.
- CVE-2006-2272: Linux SCTP allowed remote attackers to cause a denial of service (kernel panic) via incoming IP fragmented (1) COOKIE_ECHO and (2) HEARTBEAT SCTP control chunks.
- CVE-2006-2274: Linux SCTP allows remote attackers to cause a denial of service (infinite recursion and crash) via a packet that contains two or more DATA fragments, which causes an skb pointer to refer back to itself when the full message is reassembled, leading to infinite recursion in the sctp_skb_pull function.
- CVE-2006-1524: shmat: stop mprotect from giving write permission to a readonly shared memory attachment.
- CVE-2006-1863: Due to incorrect argument checking it was possible to break out of chroots on cifs filesystems.
- CVE-2006-1864: Due to incorrect argument checking it was possible to break out of chroots on smbfs filesystems.
- CVE-2006-1342: A minor information leak in SO_ORIGINAL_DST was fixed.
- CVE-2006-1056: i386/x86-64: Fix AMD x87 information leak between processes.
- CVE-2006-0741: x86_64 only: Always check that RIPs are canonical during signal handling, otherwise local attackers could crash the machine.
- CVE-2006-1523: __group_complete_signal: Removed a bogus BUG_ON which could lead to unwanted process crashes.
- CVE-2006-1527: NETFILTER SCTP conntrack: Fixed an infinite loop in sctp handling, which could be caused by a remote attacker.
- CVE-2006-1525: IPV4: Fixed a machine crash in ip_route_input that could be triggered via the "route" command from local attackers.
- CVE-2006-0095: dm-crypt: Zero key before freeing it to avoid leakage.
- CVE-2006-1242: Fix IPv4 IPID generation to avoid possible idle scans against the machine.
- CVE-2006-0744: When the user could have changed %RIP always force IRET.
- CVE-2006-0554: A XFS ftruncate() bug could expose stale data.

First, find out which kernel package to download and use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and the kernel symbols (kernel-syms*.rpm) and install it with either:
- rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
- rpm -Fhv kernel-syms*.rpm kernel-smp*.rpm for the SMP kernel image with support for up to 64 GB, or
- rpm -Fhv kernel-syms*.rpm kernel-bigsmp*.rpm for the SMP kernel image with support for up to 64 GB
In case you are using LILO as bootmanager, please make sure that you also execute the command
after installing the update for the system to remain bootable.
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.)
