The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * a logic error was found in the do_setlk() function of the Linux kernel Network File System (NFS) implementation. If a signal interrupted a lock request, the local POSIX lock was incorrectly created. This could cause a denial of service on the NFS server if a file descriptor was closed before its corresponding lock request returned. (CVE-2008-4307, Important) * a deficiency was found in the Linux kernel system call auditing implementation on 64-bit systems. This could allow a local, unprivileged user to circumvent a system call audit configuration, if that configuration filtered based on the &quot syscall&quot number or arguments. (CVE-2009-0834, Important) * Chris Evans reported a deficiency in the Linux kernel signals implementation. The clone() system call permits the caller to indicate the signal it wants to receive when its child exits. When clone() is called with the CLONE_PARENT flag, it permits the caller to clone a new child that shares the same parent as itself, enabling the indicated signal to be sent to the caller's parent (instead of the caller), even if the caller's parent has different real and effective user IDs. This could lead to a denial of service of the parent. (CVE-2009-0028, Moderate) * the sock_getsockopt() function in the Linux kernel did not properly initialize a data structure that can be directly returned to user-space when the getsockopt() function is called with SO_BSDCOMPAT optname set. This flaw could possibly lead to memory disclosure. (CVE-2009-0676, Moderate) Bug fixes: * a kernel crash may have occurred for Red Hat Enterprise Linux 4.7 guests if their guest configuration file specified &quot vif = [ &quot type=ioemu&quot ]&quot . This crash only occurred when starting guests via the &quot xm create&quot command. (BZ#477146) * a bug in IO-APIC NMI watchdog may have prevented Red Hat Enterprise Linux 4.7 from being installed on HP ProLiant DL580 G5 systems. Hangs during installation and &quot NMI received for unknown reason [xx]&quot errors may have occurred. (BZ#479184) * a kernel deadlock on some systems when using netdump through a network interface that uses the igb driver. (BZ#480579) * a possible kernel hang in sys_ptrace() on the Itanium architecture, possibly triggered by tracing a threaded process with strace. (BZ#484904) * the RHSA-2008:0665 errata only fixed the known problem with the LSI Logic LSI53C1030 Ultra320 SCSI controller, for ...
