solutions Security update for Linux kernel SuSE Linux Maintenance Web (77fd150f1962b32355a96affeee048ed)
Product(s): SuSE Linux Enterprise Server 8 for AMD64
- CVE-2005-3783: A check in ptrace(2) handling that finds out if a process is attaching to itself was incorrect and could be used by a local attacker to crash the machine.
- CVE-2005-3044: Missing sockfd_put() calls in routing_ioctl() leaked file handles which in turn could exhaust system memory.
- CVE-2005-2490: A stack-based buffer overflow in the sendmsg function call in the Linux kernel 2.6 and 2.4 allowed local users execute arbitrary code by calling sendmsg and modifying the message contents in another thread.
- CVE-2005-3806: A bug in IPv6 flowlabel handling code could be used by a local attacker to free non-allocated memory and in turn corrupt kernel memory and likely crash the machine.
- CVE-2005-3275: The NAT code in Linux kernel incorrectly declares a variable to be static, which allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time.
- CVE-2005-2457: A problem in decompression of files on "zisofs" filesystem was fixed.
- CVE-2005-2458: A potential buffer overflow in the zlib decompression handling in the kernel was fixed.
- CVE-2005-2459: Some return codes in zlib decoding were fixed which could have led to an attacker crashing the kernel.
- Fixed a race on the count of unused dcache entries.
- Fixed the "treason uncloaked" kernel messages that were caused by a stale pred_flags variable when the TCP snd_wnd changes.
- Allow filesystems to return NFSERR_JUKEBOX to the server by returning -ETIMEDOUT.
- Documented SCSI device scanning parameters.
- Added an NFS ACL fix for Solaris VxFS compatibility.
- Fixed an incorrect error return in ip_conntrack_expect_related.
- Add EMC Invista to SCSI LUN blacklist.
- A USB problem with the OHCI chipset was fixed.
- The TSC (timestampcount) register is now used as monotonic source for the hangcheck timer.
First, find out which kernel package to use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
- rpm -Fvh k_deflt-2.4.*.rpm for the default kernel image, or
- rpm -Fhv k_smp-2.4.*.rpm for the SMP kernel image, or
- rpm -Fhv k_numa-2.4.*.rpm for the NUMA 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.)
