The 3.13.7 stable update contains a number of important fixes across the tree.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP).
A local user could exploit this flaw to gain administrative privileges. (CVE-2014-4943)

Michael S. Tsirkin discovered an information leak in the Linux kernel's segmentation of skbs when using the zerocopy feature of vhost-net. A local attacker could exploit this flaw to gain potentially sensitive information from kernel memory. (CVE-2014-0131)

Don Bailey discovered a flaw in the LZO decompress algorithm used by the Linux kernel. An attacker could exploit this flaw to cause a denial of service (memory corruption or OOPS). (CVE-2014-4608).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been found and corrected in the Linux kernel :

Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions (CVE-2013-4514).

Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation (CVE-2014-0131).

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 (CVE-2014-4027).

Multiple integer overflows in the lzo1x_decompress_safe function in lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run (CVE-2014-4608).

Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (CVE-2014-4652).

sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (CVE-2014-4653).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call (CVE-2014-4654).

The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls (CVE-2014-4655).

Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function (CVE-2014-4656).

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 (CVE-2014-4667).

The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls (CVE-2014-4699).

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 (CVE-2014-4943).

The updated packages provides a solution for these security issues.

The SUSE Linux Enterprise 11 Service Pack 2 LTSS kernel has been updated to fix security issues on kernels on the x86_64 architecture.

The following security bugs have been fixed :

  - CVE-2012-4398: The __request_module function in     kernel/kmod.c in the Linux kernel before 3.4 did not set     a certain killable attribute, which allowed local users     to cause a denial of service (memory consumption) via a     crafted application (bnc#779488).

  - CVE-2013-2899: drivers/hid/hid-picolcd_core.c in the     Human Interface Device (HID) subsystem in the Linux     kernel through 3.11, when CONFIG_HID_PICOLCD is enabled,     allowed physically proximate attackers to cause a denial     of service (NULL pointer dereference and OOPS) via a     crafted device (bnc#835839).

  - CVE-2013-2929: The Linux kernel before 3.12.2 did not     properly use the get_dumpable function, which allowed     local users to bypass intended ptrace restrictions or     obtain sensitive information from IA64 scratch registers     via a crafted application, related to kernel/ptrace.c     and arch/ia64/include/asm/processor.h (bnc#847652).

  - CVE-2013-7263: The Linux kernel before 3.12.4 updates     certain length values before ensuring that associated     data structures have been initialized, which allowed     local users to obtain sensitive information from kernel     stack memory via a (1) recvfrom, (2) recvmmsg, or (3)     recvmsg system call, related to net/ipv4/ping.c,     net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and     net/ipv6/udp.c (bnc#857643).

  - CVE-2014-0131: Use-after-free vulnerability in the     skb_segment function in net/core/skbuff.c in the Linux     kernel through 3.13.6 allowed attackers to obtain     sensitive information from kernel memory by leveraging     the absence of a certain orphaning operation     (bnc#867723).

  - CVE-2014-0181: The Netlink implementation in the Linux     kernel through 3.14.1 did not provide a mechanism for     authorizing socket operations based on the opener of a     socket, which allowed local users to bypass intended     access restrictions and modify network configurations by     using a Netlink socket for the (1) stdout or (2) stderr     of a setuid program (bnc#875051).

  - A NULL pointer dereference flaw was found in the     rds_ib_laddr_check() function in the Linux kernel's     implementation of Reliable Datagram Sockets (RDS). A     local, unprivileged user could use this flaw to crash     the system.(CVE-2013-7339)

  - A flaw was found in the way the Linux kernel's Crypto     subsystem handled automatic loading of kernel modules.
    A local user could use this flaw to load any installed     kernel module, and thus increase the attack surface of     the running kernel.(CVE-2013-7421)

  - A flaw was found in the Linux kernel's implementation     of Unix sockets. A server polling for client-socket     data could put the peer socket on a wait list the peer     socket could then close the connection, making the     reference on the wait list no longer valid. This could     lead to bypassing the permissions on a Unix socket and     packets being injected into the stream, and could also     panic the machine (denial of service).(CVE-2013-7446)

  - The compat_sys_recvmmsg function in net/compat.c in the     Linux kernel before 3.13.2, when CONFIG_X86_X32 is     enabled, allows local users to gain privileges via a     recvmmsg system call with a crafted timeout pointer     parameter.(CVE-2014-0038)

  - Buffer overflow in the complete_emulated_mmio function     in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6     allows guest OS users to execute arbitrary code on the     host OS by leveraging a loop that triggers an invalid     memory copy affecting certain cancel_work_item     data.(CVE-2014-0049)

  - The cifs_iovec_write function in fs/cifs/file.c in the     Linux kernel through 3.13.5 does not properly handle     uncached write operations that copy fewer than the     requested number of bytes, which allows local users to     obtain sensitive information from kernel memory, cause     a denial of service (memory corruption and system     crash), or possibly gain privileges via a writev system     call with a crafted pointer.(CVE-2014-0069)

  - drivers/vhost/net.c in the Linux kernel before 3.13.10,     when mergeable buffers are disabled, does not properly     validate packet lengths, which allows guest OS users to     cause a denial of service (memory corruption and host     OS crash) or possibly gain privileges on the host OS     via crafted packets, related to the handle_rx and     get_rx_bufs functions.(CVE-2014-0077)

  - Race condition in the inet_frag_intern function in     net/ipv4/inet_fragment.c in the Linux kernel through     3.13.6 allows remote attackers to cause a denial of     service (use-after-free error) or possibly have     unspecified other impact via a large series of     fragmented ICMP Echo Request packets to a system with a     heavy CPU load.(CVE-2014-0100)

  - A flaw was found in the way the Linux kernel processed     an authenticated COOKIE_ECHO chunk during the     initialization of an SCTP connection. A remote attacker     could use this flaw to crash the system by initiating a     specially crafted SCTP handshake in order to trigger a     NULL pointer dereference on the system.(CVE-2014-0101)

  - The keyring_detect_cycle_iterator function in     security/keys/keyring.c in the Linux kernel through     3.13.6 does not properly determine whether keyrings are     identical, which allows local users to cause a denial     of service (OOPS) via crafted keyctl     commands.(CVE-2014-0102)

  - Use-after-free vulnerability in the skb_segment     function in net/core/skbuff.c in the Linux kernel     through 3.13.6 allows attackers to obtain sensitive     information from kernel memory by leveraging the     absence of a certain orphaning     operation.(CVE-2014-0131)

  - The ioapic_deliver function in virt/kvm/ioapic.c in the     Linux kernel through 3.14.1 does not properly validate     the kvm_irq_delivery_to_apic return value, which allows     guest OS users to cause a denial of service (host OS     crash) via a crafted entry in the redirection table of     an I/O APIC. NOTE: the affected code was moved to the     ioapic_service function before the vulnerability was     announced.(CVE-2014-0155)

  - It was found that the permission checks performed by     the Linux kernel when a netlink message was received     were not sufficient. A local, unprivileged user could     potentially bypass these restrictions by passing a     netlink socket as stdout or stderr to a more privileged     process and altering the output of this     process.(CVE-2014-0181)
