Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bnc#955654).

- CVE-2015-7509: fs/ext4/namei.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (system crash) via a crafted no-journal filesystem, a related issue to CVE-2013-2015 (bnc#956707).

- CVE-2015-7515: An out of bounds memory access in the aiptek USB driver could be used by physical local attackers to crash the kernel (bnc#956708).

- CVE-2015-7550: The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel did not properly use a semaphore, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls (bnc#958951).

- CVE-2015-7566: A malicious USB device could cause kernel crashes in the visor device driver (bnc#961512).

- CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel 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-2015-8215: 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-2015-8539: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c (bnc#958463).

- 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-2015-8550: Optimizations introduced by the compiler could have lead to double fetch vulnerabilities, potentially possibly leading to arbitrary code execution in backend (bsc#957988). (bsc#957988 XSA-155).

- CVE-2015-8551: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka 'Linux pciback missing sanity checks (bnc#957990).

- CVE-2015-8552: The PCI backend driver in Xen, when running on an x86 system and using Linux as the driver domain, allowed local guest administrators to generate a continuous stream of WARN messages and cause a denial of service (disk consumption) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka 'Linux pciback missing sanity checks (bnc#957990).

- CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel do 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-2015-8575: The sco_sock_bind function in net/bluetooth/sco.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#959399).

- CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not properly manage the relationship between a lock and a socket, which allowed local users to cause a denial of service (deadlock) via a crafted sctp_accept call (bnc#961509).

- CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel allowed local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov (bnc#963765).

- CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the network was considered congested. The kernel would incorrectly misinterpret the congestion as an error condition and incorrectly free/clean up the skb. When the device would then send the skb's queued, these structures would be referenced and may panic the system or allow an attacker to escalate privileges in a use-after-free scenario.(bsc#966437).

- CVE-2015-8816: A malicious USB device could cause kernel crashes in the in hub_activate() function (bnc#968010).

- CVE-2016-0723: Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call (bnc#961500).

- CVE-2016-2069: A race in invalidating paging structures that were not in use locally could have lead to disclosoure of information or arbitrary code exectution (bnc#963767).

- CVE-2016-2143: On zSeries a fork of a large process could have caused memory corruption due to incorrect page table handling. (bnc#970504, LTC#138810).

- CVE-2016-2184: A malicious USB device could cause kernel crashes in the alsa usb-audio device driver (bsc#971125).

- CVE-2016-2185: A malicious USB device could cause kernel crashes in the usb_driver_claim_interface function (bnc#971124).

- CVE-2016-2186: A malicious USB device could cause kernel crashes in the powermate device driver (bnc#970958).

- CVE-2016-2543: A missing NULL check at remove_events ioctl in the ALSA seq driver was fixed. (bsc#967972).

- CVE-2016-2544: Fix race at timer setup and close in the ALSA seq driver was fixed. (bsc#967973).

- CVE-2016-2545: A double unlink of active_list in the ALSA timer driver was fixed. (bsc#967974).

- CVE-2016-2546: A race among ALSA timer ioctls was fixed (bsc#967975).
