Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-0435     Gleb Napatov reported an issue in the KVM subsystem that     allows virtual machines to cause a denial of service of     the host machine by executing mov to/from DR     instructions.

  - CVE-2010-3699     Keir Fraser provided a fix for an issue in the Xen     subsystem. A guest can cause a denial of service on the     host by retaining a leaked reference to a device. This     can result in a zombie domain, xenwatch process hangs,     and xm command failures.

  - CVE-2010-4158     Dan Rosenberg discovered an issue in the socket filters     subsystem, allowing local unprivileged users to obtain     the contents of sensitive kernel memory.

  - CVE-2010-4162     Dan Rosenberg discovered an overflow issue in the block     I/O subsystem that allows local users to map large     numbers of pages, resulting in a denial of service due     to invocation of the out of memory killer.

  - CVE-2010-4163     Dan Rosenberg discovered an issue in the block I/O     subsystem. Due to improper validation of iov segments,     local users can trigger a kernel panic resulting in a     denial of service.

  - CVE-2010-4242     Alan Cox reported an issue in the Bluetooth subsystem.
    Local users with sufficient permission to access HCI     UART devices can cause a denial of service (NULL pointer     dereference) due to a missing check for an existing tty     write operation.

  - CVE-2010-4243     Brad Spengler reported a denial-of-service issue in the     kernel memory accounting system. By passing large     argv/envp values to exec, local users can cause the out     of memory killer to kill processes owned by other users.

  - CVE-2010-4248     Oleg Nesterov reported an issue in the POSIX CPU timers     subsystem. Local users can cause a denial of service     (Oops) due to incorrect assumptions about thread group     leader behavior.

  - CVE-2010-4249     Vegard Nossum reported an issue with the UNIX socket     garbage collector. Local users can consume all of LOWMEM     and decrease system performance by overloading the     system with inflight sockets.

  - CVE-2010-4258     Nelson Elhage reported an issue in Linux oops handling.
    Local users may be able to obtain elevated privileges if     they are able to trigger an oops with a process' fs set     to KERNEL_DS.

  - CVE-2010-4342     Nelson Elhage reported an issue in the Econet protocol.
    Remote attackers can cause a denial of service by     sending an Acorn Universal Networking packet over UDP.

    Combined with an otherwise low severity local denial of     service vulnerability (NULL pointer dereference), a     local user could obtain elevated privileges.

  - CVE-2010-4526     Eugene Teo reported a race condition in the Linux SCTP     implementation. Remote users can cause a denial of     service (kernel memory corruption) by transmitting an     ICMP unreachable message to a locked socket.

  - CVE-2010-4527     Dan Rosenberg reported two issues in the OSS soundcard     driver. Local users with access to the device (members     of group 'audio' on default Debian installations) may     access to sensitive kernel memory or cause a buffer     overflow, potentially leading to an escalation of     privileges.

  - CVE-2010-4529     Dan Rosenberg reported an issue in the Linux kernel IrDA     socket implementation on non-x86 architectures. Local     users may be able to gain access to sensitive kernel     memory via a specially crafted IRLMP_ENUMDEVICES     getsockopt call.

  - CVE-2010-4565     Dan Rosenberg reported an issue in the Linux CAN     protocol implementation. Local users can obtain the     address of a kernel heap object which might help     facilitate system exploitation.

  - CVE-2010-4649     Dan Carpenter reported an issue in the uverb handling of     the InfiniBand subsystem. A potential buffer overflow     may allow local users to cause a denial of service     (memory corruption) by passing in a large cmd.ne value.

The SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.27 and fixes various bugs and security issues.

The following security issues were fixed :

  - A local attacker could use a Oops (kernel crash) caused     by other flaws to write a 0 byte to a attacker     controlled address in the kernel. This could lead to     privilege escalation together with other issues.
    (CVE-2010-4258)

  - A overflow in sendto() and recvfrom() routines was fixed     that could be used by local attackers to potentially     crash the kernel using some socket families like L2TP.
    (CVE-2010-4160)

  - A 32bit vs 64bit integer mismatch in gdth_ioctl_alloc     could lead to memory corruption in the GDTH driver.
    (CVE-2010-4157)

  - The do_tcp_setsockopt function in net/ipv4/tcp.c in the     Linux kernel did not properly restrict TCP_MAXSEG (aka     MSS) values, which allowed local users to cause a denial     of service (OOPS) via a setsockopt call that specifies a     small value, leading to a divide-by-zero error or     incorrect use of a signed integer. (CVE-2010-4165)

  - A remote (or local) attacker communicating over X.25     could cause a kernel panic by attempting to negotiate     malformed facilities. (CVE-2010-4164)

    (CVE-2010-4169)

  - A minor heap overflow in the CAN network module was     fixed. Due to nature of the memory allocator it is     likely not exploitable. (CVE-2010-3874)

  - A memory information leak in berkely packet filter rules     allowed local attackers to read uninitialized memory of     the kernel stack. (CVE-2010-4158)

  - A local denial of service in the blockdevice layer was     fixed. (CVE-2010-4162)

  - By submitting certain I/O requests with 0 length, a     local user could have caused a kernel panic.
    (CVE-2010-4163)

  - The ethtool_get_rxnfc function in net/core/ethtool.c in     the Linux kernel did not initialize a certain block of     heap memory, which allowed local users to obtain     potentially sensitive information via an     ETHTOOL_GRXCLSRLALL ethtool command with a large     info.rule_cnt value. (CVE-2010-3861)

  - arch/x86/kvm/x86.c in the Linux kernel did not     initialize certain structure members, which allowed     local users to obtain potentially sensitive information     from kernel stack memory via read operations on the     /dev/kvm device. (CVE-2010-3881)

  - A range checking overflow in pktcdvd ioctl was fixed.
    (CVE-2010-3437)

  - The viafb_ioctl_get_viafb_info function in     drivers/video/via/ioctl.c in the Linux kernel did not     properly initialize a certain structure member, which     allowed local users to obtain potentially sensitive     information from kernel stack memory via a     VIAFB_GET_INFO ioctl call. (CVE-2010-4082)

  - The ipc subsystem in the Linux kernel did not initialize     certain structures, which allowed local users to obtain     potentially sensitive information from kernel stack     memory via vectors related to the (1) compat_sys_semctl,     (2) compat_sys_msgctl, and (3) compat_sys_shmctl     functions in ipc/compat.c; and the (4)     compat_sys_mq_open and (5) compat_sys_mq_getsetattr     functions in ipc/compat_mq.c. (CVE-2010-4073)

  - The copy_shmid_to_user function in ipc/shm.c in the     Linux kernel did not initialize a certain structure,     which allowed local users to obtain potentially     sensitive information from kernel stack memory via     vectors related to the shmctl system call and the 'old     shm interface.'. (CVE-2010-4072)

  - The copy_semid_to_user function in ipc/sem.c in the     Linux kernel did not initialize a certain structure,     which allowed local users to obtain potentially     sensitive information from kernel stack memory via a (1)     IPC_INFO, (2) SEM_INFO, (3) IPC_STAT, or (4) SEM_STAT     command in a semctl system call. (CVE-2010-4083)
