This kernel update for openSUSE 11.0 fixes some bugs and several security problems. The following security issues are fixed: CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload. CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets. CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings. CVE-2010-0003: An information leakage on fatal signals on x86_64 machines was fixed. CVE-2009-4138: drivers/firewire/ohci.c in the Linux kernel, when packet-per-buffer mode is used, allows local users to cause a denial of service or possibly have unknown other impact via an unspecified ioctl associated with receiving an ISO packet that contains zero in the payload-length field. CVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service , and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal. CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel 126.96.36.199 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file. CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow attackers to cause a denial of service via vectors possibly related to a memory-consumption attack. CVE-2009-3547: A race condition in the pipe system call could be used by local attackers to hang the machine. The kernel in Moblin 2.0 uses NULL ptr protection which avoids code execution possibilities. CVE-2009-2903: Memory leak in the AppleTalk subsystem in the Linux kernel 2.4.x through 188.8.131.52 and 2.6.x through 2.6.31, when the AppleTalk and ipddp modules are loaded but the ipddp &qt N &qt device is not found, allows remote attackers to cause a denial of service via IP-DDP datagrams. CVE-2009-3621: net/unix/af_unix.c in the Linux kernel 184.108.40.206 and earlier allows local users to cause a denial of service by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket. CVE-2009-3612: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 220.127.116.11 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors. CVE-2009-3620: The ATI Rage 128 driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine state initialization, which allows local users to cause a denial of service or possibly gain privileges via unspecified ioctl calls. CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state. CVE-2009-3286: NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails. CVE-2009-2910: arch/x86/ia32/ia32entry.S in the Linux kernel before 18.104.22.168 on the x86_64 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode. CVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function"s tendency to &qt return the same value over and over again for long stretches of time. &qt CVE-2009-2848: The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit. CVE-2009-3002: The Linux kernel before 2.6.31-rc7 does not initialize certain data structures within getname functions, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_APPLETALK socket, related to the atalk_getname function in net/appletalk/ddp.c; an AF_IRDA socket, related to the irda_getname function in net/irda/af_irda.c; an AF_ECONET socket, related to the econet_getname function in net/econet/af_econet.c; an AF_NETROM socket, related to the nr_getname function in net/netrom/af_netrom.c; an AF_ROSE socket, related to the rose_getname function in net/rose/af_rose.c; or a raw CAN socket, related to the raw_getname function in net/can/raw.c. CVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the Linux kernel before 22.214.171.124 allow remote CIFS servers to cause a denial of service and possibly have unspecified other impact via a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.
