The remote Debian host is running a version of the Linux kernel prior to 3.2.73-2+deb7u1 on Debian 7 or is running a version of the Linux kernel prior to 3.16.7-ckt20-1+deb8u1 on Debian 8. It is, therefore, affected by the following vulnerabilities :

  - A use-after-free error exists in the unix_dgram_poll()     function within file net/unix/af_unix.c. A local     attacker can exploit this, via specially crafted     epoll_ctl calls, to cause a denial of service condition     or bypass AF_UNIX socket permissions. (CVE-2013-7446)

  - A NULL pointer dereference flaw exists in the     slhc_init() function within file drivers/net/slip/slhc.c     due to improper validation of slot numbers. A local     attacker can exploit this, via specially crafted     PPPIOCSMAXCID IOCTL calls, to cause a denial of service     condition. (CVE-2015-7799)

  - A flaw exists in the usbvision driver that allows a     local attacker, via a nonzero bInterfaceNumber value in     a USB device descriptor, to cause a kernel panic,     resulting in a denial of service condition.
    (CVE-2015-7833)

  - An infinite loop condition exists in the KVM subsystem     on some unspecified CPU chipsets. A local attacker who     has sufficient privileges within a virtual guest OS can     exploit this issue, by triggering many debug exceptions,     to cause a denial of service condition. (CVE-2015-8104)

  - A flaw exists in the truncate_space_check() function     within file /fs/btrfs/inode.c due to improper handling     of compressed file extents. A local attacker can exploit     this, via a clone action, to disclose sensitive     pre-truncation information from a file. (CVE-2015-8374)

  - A NULL pointer dereference flaw exists in the     inet_autobind() function within file net/ipv4/af_inet.c     when handling connection attempts via IPv6. A local     attacker can exploit this, via a specially crafted     SOCK_RAW application that makes use of CLONE_NEWUSER     support, to cause a denial of service condition or     possibly gain elevated privileges. (CVE-2015-8543)

The openSUSE 13.1 kernel was updated to receive various security and bugfixes.

Following security bugs were fixed :

  - CVE-2016-0728: A reference leak in keyring handling with     join_session_keyring() could lead to local attackers     gain root privileges. (bsc#962075).

  - CVE-2015-7550: A local user could have triggered a race     between read and revoke in keyctl (bnc#958951).

  - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect     functions in drivers/net/ppp/pptp.c in the Linux kernel     did not verify an address length, which allowed local     users to obtain sensitive information from kernel memory     and bypass the KASLR protection mechanism via a crafted     application (bnc#959190).

  - CVE-2015-8543: The networking implementation in the     Linux kernel did not validate protocol identifiers for     certain protocol families, which allowed local users to     cause a denial of service (NULL function pointer     dereference and system crash) or possibly gain     privileges by leveraging CLONE_NEWUSER support to     execute a crafted SOCK_RAW application (bnc#958886).

  - CVE-2014-8989: The Linux kernel did not properly     restrict dropping of supplemental group memberships in     certain namespace scenarios, which allowed local users     to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category     that is more restrictive than the entry for the other     category, aka a 'negative groups' issue, related to     kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c (bnc#906545).

  - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux     kernel on the x86_64 platform mishandles IRET faults in     processing NMIs that occurred during userspace     execution, which might allow local users to gain     privileges by triggering an NMI (bnc#937969).

  - CVE-2015-7799: The slhc_init function in     drivers/net/slip/slhc.c in the Linux kernel through     4.2.3 did not ensure that certain slot numbers are     valid, which allowed local users to cause a denial of     service (NULL pointer dereference and system crash) via     a crafted PPPIOCSMAXCID ioctl call (bnc#949936).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel     through 4.2.6, and Xen 4.3.x through 4.6.x, allowed     guest OS users to cause a denial of service (host OS     panic or hang) by triggering many #DB (aka Debug)     exceptions, related to svm.c (bnc#954404).

  - CVE-2015-5307: The KVM subsystem in the Linux kernel     through 4.2.6, and Xen 4.3.x through 4.6.x, allowed     guest OS users to cause a denial of service (host OS     panic or hang) by triggering many #AC (aka Alignment     Check) exceptions, related to svm.c and vmx.c     (bnc#953527).

  - CVE-2014-9529: Race condition in the key_gc_unused_keys     function in security/keys/gc.c in the Linux kernel     allowed local users to cause a denial of service (memory     corruption or panic) or possibly have unspecified other     impact via keyctl commands that trigger access to a key     structure member during garbage collection of a key     (bnc#912202).

  - CVE-2015-7990: Race condition in the rds_sendmsg     function in net/rds/sendmsg.c in the Linux kernel     allowed local users to cause a denial of service (NULL     pointer dereference and system crash) or possibly have     unspecified other impact by using a socket that was not     properly bound. NOTE: this vulnerability exists because     of an incomplete fix for CVE-2015-6937 (bnc#952384     953052).

  - CVE-2015-6937: The __rds_conn_create function in     net/rds/connection.c in the Linux kernel allowed local     users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact by using a socket that was not     properly bound (bnc#945825).

  - CVE-2015-7885: The dgnc_mgmt_ioctl function in     drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel     through 4.3.3 did not initialize a certain structure     member, which allowed local users to obtain sensitive     information from kernel memory via a crafted application     (bnc#951627).

  - CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in     the Linux kernel did not validate attempted changes to     the MTU value, which allowed context-dependent attackers     to cause a denial of service (packet loss) via a value     that is (1) smaller than the minimum compliant value or     (2) larger than the MTU of an interface, as demonstrated     by a Router Advertisement (RA) message that is not     validated by a daemon, a different vulnerability than     CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is     limited to the NetworkManager product (bnc#955354).

  - CVE-2015-8767: A case can occur when sctp_accept() is     called by the user during a heartbeat timeout event     after the 4-way handshake. Since sctp_assoc_migrate()     changes both assoc->base.sk and assoc->ep, the     bh_sock_lock in sctp_generate_heartbeat_event() will be     taken with the listening socket but released with the     new association socket. The result is a deadlock on any     future attempts to take the listening socket lock.
    (bsc#961509)

  - CVE-2015-8575: Validate socket address length in     sco_sock_bind() to prevent information leak     (bsc#959399).

  - CVE-2015-8551, CVE-2015-8552: xen/pciback: For     XEN_PCI_OP_disable_msi[|x] only disable if device has     MSI(X) enabled (bsc#957990).

  - CVE-2015-8550: Compiler optimizations in the XEN PV     backend drivers could have lead to double fetch     vulnerabilities, causing denial of service or arbitrary     code execution (depending on the configuration)     (bsc#957988).
