SUSE-SU-2015:0581-1

The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to fix various bugs and security issues.

The following security bugs have been fixed:

* 

  CVE-2014-1739: The media_device_enum_entities function in
  drivers/media/media-device.c in the Linux kernel before 3.14.6 does
  not initialize a certain data structure, which allows local users to
  obtain sensitive information from kernel memory by leveraging
  /dev/media0 read access for a MEDIA_IOC_ENUM_ENTITIES ioctl call
  (bnc#882804).

* 

  CVE-2014-4171: mm/shmem.c in the Linux kernel through 3.15.1 does not
  properly implement the interaction between range notification and
  hole punching, which allows local users to cause a denial of service
  (i_mutex hold) by using the mmap system call to access a hole, as
  demonstrated by interfering with intended shmem activity by blocking
  completion of (1) an MADV_REMOVE madvise call or (2) an
  FALLOC_FL_PUNCH_HOLE fallocate call (bnc#883518).

* 

  CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel through
  3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and
  the sep CPU feature flag is set, allows local users to cause a denial
  of service (OOPS and system crash) via an invalid syscall number, as
  demonstrated by number 1000 (bnc#883724).

* 

  CVE-2014-4667: The sctp_association_free function in
  net/sctp/associola.c in the Linux kernel before 3.15.2 does not
  properly manage a certain backlog value, which allows remote
  attackers to cause a denial of service (socket outage) via a crafted
  SCTP packet (bnc#885422).

* 

  CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the
  Linux kernel through 3.15.6 allows local users to gain privileges by
  leveraging data-structure differences between an l2tp socket and an
  inet socket (bnc#887082).

* 

  CVE-2014-5077: The sctp_assoc_update function in net/sctp/associola.c
  in the Linux kernel through 3.15.8, when SCTP authentication is
  enabled, allows remote attackers to cause a denial of service (NULL
  pointer dereference and OOPS) by starting to establish an association
  between two endpoints immediately after an exchange of INIT and INIT
  ACK chunks to establish an earlier association between these
  endpoints in the opposite direction (bnc#889173).

* 

  CVE-2014-5471: Stack consumption vulnerability in the
  parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the
  Linux kernel through 3.16.1 allows local users to cause a denial of
  service (uncontrolled recursion, and system crash or reboot) via a
  crafted iso9660 image with a CL entry referring to a directory entry
  that has a CL entry. (bnc#892490)

* 

  CVE-2014-5472: The parse_rock_ridge_inode_internal function in
  fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users
  to cause a denial of service (unkillable mount process) via a crafted
  iso9660 image with a self-referential CL entry. (bnc#892490)

* 

  CVE-2014-2706: Race condition in the mac80211 subsystem in the Linux
  kernel before 3.13.7 allows remote attackers to cause a denial of
  service (system crash) via network traffic that improperly interacts
  with the WLAN_STA_PS_STA state (aka power-save mode), related to
  sta_info.c and tx.c. (bnc#871797)

* 

  CVE-2014-4027: The rd_build_device_space function in
  drivers/target/target_core_rd.c in the Linux kernel before 3.14 does
  not properly initialize a certain data structure, which allows local
  users to obtain sensitive information from ramdisk_mcp memory by
  leveraging access to a SCSI initiator. (bnc#882639)

* 

  CVE-2014-3153 The futex_requeue function in kernel/futex.c in the
  Linux kernel through 3.14.5 does not ensure that calls have two
  different futex addresses, which allows local users to gain
  privileges via a crafted FUTEX_REQUEUE command that facilitates
  unsafe waiter modification. (bnc#880892)

The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to fix various bugs and security issues.

Following security bugs were fixed: CVE-2013-1979: The scmsetcred function in include/net/scm.h in the Linux kernel before 3.8.11 uses incorrect uid and gid values during credentials passing, which allows local users to gain privileges via a crafted application (bnc#816708).

CVE-2014-1739: The mediadeviceenumentities function in drivers/media/media-device.c in the Linux kernel before 3.14.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging /dev/media0 read access for a MEDIAIOCENUMENTITIES ioctl call (bnc#882804).

CVE-2014-4171: mm/shmem.c in the Linux kernel through 3.15.1 does not properly implement the interaction between range notification and hole punching, which allows local users to cause a denial of service (imutex hold) by using the mmap system call to access a hole, as demonstrated by interfering with intended shmem activity by blocking completion of (1) an MADVREMOVE madvise call or (2) an FALLOCFLPUNCH_HOLE fallocate call (bnc#883518).

CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000 (bnc#883724).

CVE-2014-4667: The sctpassociationfree function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet (bnc#885422).

CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket (bnc#887082).

CVE-2014-5077: The sctpassocupdate function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction (bnc#889173).

CVE-2014-5471: Stack consumption vulnerability in the parserockridgeinodeinternal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (uncontrolled recursion, and system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that has a CL entry. (bnc#892490)

CVE-2014-5472: The parserockridgeinodeinternal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a self-referential CL entry. (bnc#892490)

CVE-2014-2706: Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLANSTAPSSTA state (aka power-save mode), related to stainfo.c and tx.c. (bnc#871797)

CVE-2014-4027: The rdbuilddevicespace function in drivers/target/targetcorerd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdiskmcp memory by leveraging access to a SCSI initiator. (bnc#882639)

CVE-2014-3153 The futexrequeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEXREQUEUE command that facilitates unsafe waiter modification. (bnc#880892)
