This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs.

The following security issues were fixed :

  - The code for evaluating LDM partitions (in     fs/partitions/ldm.c) contained bugs that could crash the     kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-1012)

  - Boundschecking was missing in AARESOLVE_OFFSET, which     allowed local attackers to overwrite kernel memory and     so escalate privileges or crash the kernel.
    (CVE-2011-1573)

  - When using a setuid root mount.cifs, local users could     hijack password protected mounted CIFS shares of other     local users. (CVE-2011-1585)

  - Kernel information via the TPM devices could by used by     local attackers to read kernel memory. (CVE-2011-1160)

  - The Linux kernel automatically evaluated partition     tables of storage devices. The code for evaluating EFI     GUID partitions (in fs/partitions/efi.c) contained a bug     that causes a kernel oops on certain corrupted GUID     partition tables, which might be used by local attackers     to crash the kernel or potentially execute code.
    (CVE-2011-1577)

  - In the IrDA module, length fields provided by a peer for     names and attributes may be longer than the destination     array sizes and were not checked, this allowed local     attackers (close to the irda port) to potentially     corrupt memory. (CVE-2011-1180)

  - A system out of memory condition (denial of service)     could be triggered with a large socket backlog,     exploitable by local users. This has been addressed by     backlog limiting. (CVE-2010-4251)

  - The Radeon GPU drivers in the Linux kernel did not     properly validate data related to the AA resolve     registers, which allowed local users to write to     arbitrary memory locations associated with (1) Video RAM     (aka VRAM) or (2) the Graphics Translation Table (GTT)     via crafted values. (CVE-2011-1016)

  - When parsing the FAC_NATIONAL_DIGIS facilities field, it     was possible for a remote host to provide more     digipeaters than expected, resulting in heap corruption.
    (CVE-2011-1493)

  - Local attackers could send signals to their programs     that looked like coming from the kernel, potentially     gaining privileges in the context of setuid programs.
    (CVE-2011-1182)

  - The code for evaluating Mac partitions (in     fs/partitions/mac.c) contained a bug that could crash     the kernel for certain corrupted Mac partitions.
    (CVE-2011-1010)

  - The code for evaluating OSF partitions (in     fs/partitions/osf.c) contained a bug that leaks data     from kernel heap memory to userspace for certain     corrupted OSF partitions. (CVE-2011-1163)

  - Specially crafted requests may be written to     /dev/sequencer resulting in an underflow when     calculating a size for a copy_from_user() operation in     the driver for MIDI interfaces. On x86, this just     returns an error, but it could have caused memory     corruption on other architectures. Other malformed     requests could have resulted in the use of uninitialized     variables. (CVE-2011-1476)

  - Due to a failure to validate user-supplied indexes in     the driver for Yamaha YM3812 and OPL-3 chips, a     specially crafted ioctl request could have been sent to     /dev/sequencer, resulting in reading and writing beyond     the bounds of heap buffers, and potentially allowing     privilege escalation. (CVE-2011-1477)

  - A information leak in the XFS geometry calls could be     used by local attackers to gain access to kernel     information. (CVE-2011-0191)

  - The sctp_rcv_ootb function in the SCTP implementation in     the Linux kernel allowed remote attackers to cause a     denial of service (infinite loop) via (1) an Out Of The     Blue (OOTB) chunk or (2) a chunk of zero length.
    (CVE-2010-0008)

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-228:02 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system.  The     kernel handles the basic functions of the operating system:  memory allocation, process allocation, device     input and output, etc.
    Security issues fixed with this release:
    CVE-2011-1020     The proc filesystem implementation in the Linux kernel 2.6.37 and earlier does not restrict access to the     /proc directory tree of a process after this process performs an exec of a setuid program, which allows     local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write     system calls.
    CVE-2011-3347     CVE-2011-3638     No information available at the time of writing, see the CVE link below.
    CVE-2011-4110     The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allows local users to     cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined     key and updating a negative key into a fully instantiated key.
    CVE-2011-1162     The tpm_read function in the Linux kernel 2.6 does not properly clear memory, which might allow local     users to read the results of the previous TPM command.
    CVE-2011-1577     Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38     and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have     unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.
    CVE-2012-0056     The mem_write function in Linux kernel 2.6.39 and other versions, when ASLR is disabled, does not properly     check permissions when writing to /proc/<pid>/mem, which allows local users to gain privileges by     modifying process memory, as demonstrated by Mempodipper.
    CVE-2011-2494     CVE-2011-2699     CVE-2011-2905     CVE-2011-3188     CVE-2011-3191     CVE-2011-3353     CVE-2011-3359     CVE-2011-3363     CVE-2011-3593     CVE-2011-4326     CVE-2011-4127     No information available at the time of writing, please refer to the CVE links     below.

  - A missing validation of a null-terminated string data     structure element in the bnep_sock_ioctl() function     could allow a local user to cause an information leak or     a denial of service. (CVE-2011-1079, Moderate)

  - Missing error checking in the way page tables were     handled in the Xen hypervisor implementation could allow     a privileged guest user to cause the host, and the     guests, to lock up. (CVE-2011-1166, Moderate)

  - A flaw was found in the way the Xen hypervisor     implementation checked for the upper boundary when     getting a new event channel port. A privileged guest     user could use this flaw to cause a denial of service or     escalate their privileges. (CVE-2011-1763, Moderate)

  - The start_code and end_code values in '/proc/[pid]/stat'     were not protected. In certain scenarios, this flaw     could be used to defeat Address Space Layout     Randomization (ASLR). (CVE-2011-0726, Low)

  - A missing initialization flaw in the     sco_sock_getsockopt() function could allow a local,     unprivileged user to cause an information leak.
    (CVE-2011-1078, Low)

  - A missing validation of a null-terminated string data     structure element in the do_replace() function could     allow a local user who has the CAP_NET_ADMIN capability     to cause an information leak. (CVE-2011-1080, Low)

  - A buffer overflow flaw in the DEC Alpha OSF partition     implementation in the Linux kernel could allow a local     attacker to cause an information leak by mounting a disk     that contains specially crafted partition tables.
    (CVE-2011-1163, Low)

  - Missing validations of null-terminated string data     structure elements in the do_replace(),     compat_do_replace(), do_ipt_get_ctl(),     do_ip6t_get_ctl(), and do_arpt_get_ctl() functions could     allow a local user who has the CAP_NET_ADMIN capability     to cause an information leak. (CVE-2011-1170,     CVE-2011-1171, CVE-2011-1172, Low)

  - A heap overflow flaw in the Linux kernel's EFI GUID     Partition Table (GPT) implementation could allow a local     attacker to cause a denial of service by mounting a disk     that contains specially crafted partition tables.

The openSUSE 11.4 kernel was updated to 2.6.37.6 fixing lots of bugs and security issues.

Following security issues have been fixed: CVE-2011-1493: In the rose networking stack, when parsing the FAC_NATIONAL_DIGIS facilities field, it was possible for a remote host to provide more digipeaters than expected, resulting in heap corruption. Check against ROSE_MAX_DIGIS to prevent overflows, and abort facilities parsing on failure.

CVE-2011-1182: Local attackers could send signals to their programs that looked like coming from the kernel, potentially gaining privileges in the context of setuid programs.

CVE-2011-1478: An issue in the core GRO code where an skb belonging to an unknown VLAN is reused could result in a NULL pointer dereference.

CVE-2011-1476: Specially crafted requests may be written to /dev/sequencer resulting in an underflow when calculating a size for a copy_from_user() operation in the driver for MIDI interfaces. On x86, this just returns an error, but it could have caused memory corruption on other architectures. Other malformed requests could have resulted in the use of uninitialized variables.

CVE-2011-1477: Due to a failure to validate user-supplied indexes in the driver for Yamaha YM3812 and OPL-3 chips, a specially crafted ioctl request could have been sent to /dev/sequencer, resulting in reading and writing beyond the bounds of heap buffers, and potentially allowing privilege escalation.

CVE-2011-0191: A information leak in the XFS geometry calls could be used by local attackers to gain access to kernel information.

CVE-2011-0711: A stack memory information leak in the xfs FSGEOMETRY_V1 ioctl was fixed.

CVE-2011-0521: The dvb_ca_ioctl function in drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel did not check the sign of a certain integer field, which allowed local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a negative value.

CVE-2011-1010: The code for evaluating Mac partitions (in fs/partitions/mac.c) contained a bug that could crash the kernel for certain corrupted Mac partitions.

CVE-2011-0712: Multiple buffer overflows in the caiaq Native Instruments USB audio functionality in the Linux kernel might have allowed attackers to cause a denial of service or possibly have unspecified other impact via a long USB device name, related to (1) the snd_usb_caiaq_audio_init function in sound/usb/caiaq/audio.c and (2) the snd_usb_caiaq_midi_init function in sound/usb/caiaq/midi.c.

CVE-2011-1013: A signedness issue in the drm ioctl handling could be used by local attackers to potentially overflow kernel buffers and execute code.

CVE-2011-1082: The epoll subsystem in Linux did not prevent users from creating circular epoll file structures, potentially leading to a denial of service (kernel deadlock).

CVE-2010-4650: A kernel buffer overflow in the cuse server module was fixed, which might have allowed local privilege escalation. However only CUSE servers could exploit it and /dev/cuse is normally restricted to root.

CVE-2011-1093: A bug was fixed in the DCCP networking stack where the order of dccp_rcv_state_process() still permitted reception even after closing the socket. A Reset after close thus causes a NULL pointer dereference by not preventing operations on an already torn-down socket.

CVE-2011-1163: The code for evaluating OSF partitions (in fs/partitions/osf.c) contained a bug that leaks data from kernel heap memory to userspace for certain corrupted OSF partitions.

CVE-2011-1012: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained a bug that could crash the kernel for certain corrupted LDM partitions.

CVE-2011-1581: Doing bridging with devices with more than 16 receive queues could crash the kernel.

CVE-2011-1160: Kernel information via the TPM devices could by used by local attackers to read kernel memory.

CVE-2011-1577: The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code.

CVE-2011-1180: In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory.

CVE-2011-1016: The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values.
