CESA-2005:420: Updated kernel packages available for CentOS Linux 4 Update 1

Description

Updated kernel packages are now available as part of ongoing support and maintenance of CentOS Linux version 4. This is the first regular update. [Updated 9 August 2005] The advisory text has been updated to show that this update also contained fixes for the security issues named CAN-2005-0209 and CAN-2005-0937. No changes have been made to the packages associated with this advisory.

The Linux kernel handles the basic functions of the operating system. This is the first regular kernel update to CentOS Linux 4. A flaw affecting the auditing code was discovered. On Itanium architectures a local user could use this flaw to cause a denial of service (crash). This issue is rated as having important security impact (CAN-2005-0136). A flaw was discovered in the servicing of a raw device ioctl. A local user who has access to raw devices could use this flaw to write to kernel memory and cause a denial of service or potentially gain privileges. This issue is rated as having moderate security impact (CAN-2005-1264). A flaw in fragment forwarding was discovered that affected the netfilter subsystem for certain network interface cards. A remote attacker could send a set of bad fragments and cause a denial of service (system crash). Acenic and SunGEM network interfaces were the only adapters affected, which are in widespread use. (CAN-2005-0209) A flaw in the futex functions was discovered affecting the Linux 2.6 kernel. A local user could use this flaw to cause a denial of service (system crash). (CAN-2005-0937) New features introduced by this update include: - Fixed TCP BIC congestion handling. - Diskdump support for more controllers (megaraid, SATA) - Device mapper multipath support - AMD64 dual core support. - Intel ICH7 hardware support. There were many bug fixes in various parts of the kernel. The ongoing effort to resolve these problems has resulted in a marked improvement in the reliability and scalability of CentOS Linux 4. The following device drivers have been upgraded to new versions: ata_piix -------- 1.03 bonding --------- 2.6.1 e1000 ----------- 5.6.10.1-k2-NAPI e100 ------------ 3.3.6-k2-NAPI ibmveth --------- 1.03 libata ---------- 1.02 to 1.10 lpfc ------------ 0:8.0.16 to 0:8.0.16.6_x2 megaraid_mbox --- 2.20.4.0 to 2.20.4.5 megaraid_mm ----- 2.20.2.0-rh1 to 2.20.2.5 sata_nv --------- 0.03 to 0.6 sata_promise ---- 1.00 to 1.01 sata_sil -------- 0.8 sata_sis -------- 0.5 sata_svw -------- 1.05 sata_sx4 -------- 0.7 sata_via -------- 1.0 sata_vsc -------- 1.0 tg3 ------------- 3.22-rh ipw2100 --------- 1.0.3 ipw2200 --------- 1.0.0 All CentOS Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
