| Description: | The Linux kernel handles the basic functions of the operating system.
This is the second regular kernel update to Red Hat Enterprise Linux 4.
New features introduced in this update include: - Audit support - systemtap - kprobes, relayfs - Keyring support - iSCSI Initiator - iscsi_sfnet 4:0.1.11-1 - Device mapper multipath support - Intel dual core support - esb2 chipset support - Increased exec-shield coverage - Dirty page tracking for HA systems - Diskdump -- allow partial diskdumps and directing to swap
There were several 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 Red Hat Enterprise Linux 4.
The following security bugs were fixed in this update, detailed below with corresponding CAN names available from the Common Vulnerabilities and Exposures project (cve.mitre.org):
- flaws in ptrace() syscall handling on 64-bit systems that allowed a local user to cause a denial of service (crash) (CAN-2005-0756, CAN-2005-1761, CAN-2005-1762, CAN-2005-1763)
- flaws in IPSEC network handling that allowed a local user to cause a denial of service or potentially gain privileges (CAN-2005-2456, CAN-2005-2555)
- a flaw in sendmsg() syscall handling on 64-bit systems that allowed a local user to cause a denial of service or potentially gain privileges (CAN-2005-2490)
- a flaw in sendmsg() syscall handling that allowed a local user to cause a denial of service by altering hardware state (CAN-2005-2492)
- a flaw that prevented the topdown allocator from allocating mmap areas all the way down to address zero (CAN-2005-1265)
- flaws dealing with keyrings that could cause a local denial of service (CAN-2005-2098, CAN-2005-2099)
- a flaw in the 4GB split patch that could allow a local denial of service (CAN-2005-2100)
- a xattr sharing bug in the ext2 and ext3 file systems that could cause default ACLs to disappear (CAN-2005-2801)
- a flaw in the ipt_recent module on 64-bit architectures which could allow a remote denial of service (CAN-2005-2872)
The following device drivers have been upgraded to new versions:
