The following security bugs were fixed:

Security update for the Linux Kernel

The SUSE Linux Enterprise 15 azure kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2018-9363: Fixed an integer overflow that could have been used for an out of bounds write with no additional execution privileges needed. User interaction is not needed for exploitation (bsc#1105292).
  • CVE-2018-6555: The irda_setsockopt function in net/irda/af_irda.c was fixed in drivers/staging/irda/net/af_irda.c that allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bsc#1106511).
  • CVE-2018-6554: Fixed memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bsc#1106509).
  • CVE-2018-18710: An information leak was fixed in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c that could have been used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bsc#1113751).
  • CVE-2018-18445: Fixed faulty computation of numeric bounds in the BPF verifier that now permits out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandled 32-bit right shifts (bsc#1112372).
  • CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c was fixed that was vulnerable to sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations. (bsc#1108399).
  • CVE-2018-16658: An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c was fixed that could have leed to be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 (bsc#1107689).
  • CVE-2018-15572: The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c was not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks. (bsc#1102517)
  • CVE-2018-14633: A security flaw was fixed in the chap_server_compute_md5() function in the ISCSI target code in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely (bsc#1107829).
  • CVE-2018-14617: A NULL pointer dereference and panic in hfsplus_lookup() was fixed when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory. (bsc#1102870)
  • CVE-2018-14613: An invalid pointer dereference in io_ctl_map_page() was fixed when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c. (bsc#1102896)
  • CVE-2018-13095: A denial of service (memory corruption and BUG) was fixed to prevent a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork. (bsc#1099999)
  • CVE-2018-13093: A NULL pointer dereference and panic in lookup_slow() on a NULL was fixed to prevent pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that cached inodes are free during…

Security update for the Linux Kernel

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).
  • CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removed entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry could remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769).
  • CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).

  • CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).
  • CVE-2017-18224: fs/ocfs2/aops.c omitted use of a semaphore and consequently had a race condition for access to the extent tree during read operations in DIRECT mode, which allowed local users to cause a denial of service (BUG) by modifying a certain e_cpos field (bnc#1084831).

Security update for the Linux Kernel

The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152).
  • CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removed entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry could remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769).
  • CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751).
  • CVE-2018-18445: Faulty computation of numeric bounds in the BPF verifier permitted out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandled 32-bit right shifts (bnc#1112372).
  • CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825).
  • CVE-2017-18224: fs/ocfs2/aops.c omitted use of a semaphore and consequently had a race condition for access to the extent tree during read operations in DIRECT mode, which allowed local users to cause a denial of service (BUG) by modifying a certain e_cpos field (bnc#1084831).
