openSUSE Security Update : kernel (kernel-951)

Critical Nessus Plugin ID 40012

Synopsis

The remote openSUSE host is missing a security update.

Description

This kernel update for openSUSE 11.0 fixes some bugs and several security problems.

The following security issues are fixed: A local denial of service problem in the splice(2) system call.

CVE-2009-1630: The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.

CVE-2009-0834: The audit_syscall_entry function in the Linux kernel on the x86_64 platform did not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass certain syscall audit configurations via crafted syscalls.

CVE-2009-1072: nfsd in the Linux kernel did not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

CVE-2009-0835 The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod.

CVE-2009-1439: Buffer overflow in fs/cifs/connect.c in CIFS in the Linux kernel 2.6.29 and earlier allows remote attackers to cause a denial of service (crash) or potential code execution via a long nativeFileSystem field in a Tree Connect response to an SMB mount request.

This requires that kernel can be made to mount a 'cifs' filesystem from a malicious CIFS server.

CVE-2009-1337: The exit_notify function in kernel/exit.c in the Linux kernel did not restrict exit signals when the CAP_KILL capability is held, which allows local users to send an arbitrary signal to a process by running a program that modifies the exit_signal field and then uses an exec system call to launch a setuid application.

CVE-2009-0859: The shm_get_stat function in ipc/shm.c in the shm subsystem in the Linux kernel, when CONFIG_SHMEM is disabled, misinterprets the data type of an inode, which allows local users to cause a denial of service (system hang) via an SHM_INFO shmctl call, as demonstrated by running the ipcs program. (SUSE is enabling CONFIG_SHMEM, so is by default not affected, the fix is just for completeness).

CVE-2009-1242: The vmx_set_msr function in arch/x86/kvm/vmx.c in the VMX implementation in the KVM subsystem in the Linux kernel on the i386 platform allows guest OS users to cause a denial of service (OOPS) by setting the EFER_LME (aka 'Long mode enable') bit in the Extended Feature Enable Register (EFER) model-specific register, which is specific to the x86_64 platform.

CVE-2009-1265: Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel might allow attackers to obtain sensitive information via a large length value, which causes 'garbage' memory to be sent.

CVE-2009-0028: The clone system call in the Linux kernel allows local users to send arbitrary signals to a parent process from an unprivileged child process by launching an additional child process with the CLONE_PARENT flag, and then letting this new process exit.

CVE-2009-0675: The skfp_ioctl function in drivers/net/skfp/skfddi.c in the Linux kernel permits SKFP_CLR_STATS requests only when the CAP_NET_ADMIN capability is absent, instead of when this capability is present, which allows local users to reset the driver statistics, related to an 'inverted logic' issue.

CVE-2009-0676: The sock_getsockopt function in net/core/sock.c in the Linux kernel does not initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel memory via an SO_BSDCOMPAT getsockopt request.

CVE-2009-0322: drivers/firmware/dell_rbu.c in the Linux kernel allows local users to cause a denial of service (system crash) via a read system call that specifies zero bytes from the (1) image_type or (2) packet_size file in /sys/devices/platform/dell_rbu/.

CVE-2009-0269: fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index.

CVE-2009-0065: Buffer overflow in net/sctp/sm_statefuns.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel allows remote attackers to have an unknown impact via an FWD-TSN (aka FORWARD-TSN) chunk with a large stream ID.

Some other non-security bugs were fixed, please see the RPM changelog.

Solution

Update the affected kernel packages.
