| NASL family | Debian Local Security Checks | | NASL id | DEBIAN_DSA-3434.NASL | | description | Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak.
- CVE-2015-7513 It was discovered that a local user permitted to use the x86 KVM subsystem could configure the PIT emulation to cause a denial of service (crash).
- CVE-2015-7550 Dmitry Vyukov discovered a race condition in the keyring subsystem that allows a local user to cause a denial of service (crash).
- CVE-2015-8543 It was discovered that a local user permitted to create raw sockets could cause a denial-of-service by specifying an invalid protocol number for the socket.
The attacker must have the CAP_NET_RAW capability.
- CVE-2015-8550 Felix Wilhelm of ERNW discovered that the Xen PV backend drivers may read critical data from shared memory multiple times. This flaw can be used by a guest kernel to cause a denial of service (crash) on the host, or possibly for privilege escalation.
- CVE-2015-8551 / CVE-2015-8552 Konrad Rzeszutek Wilk of Oracle discovered that the Xen PCI backend driver does not adequately validate the device state when a guest configures MSIs. This flaw can be used by a guest kernel to cause a denial of service (crash or disk space exhaustion) on the host.
- CVE-2015-8569 Dmitry Vyukov discovered a flaw in the PPTP sockets implementation that leads to an information leak to local users.
- CVE-2015-8575 David Miller discovered a flaw in the Bluetooth SCO sockets implementation that leads to an information leak to local users.
- CVE-2015-8709 Jann Horn discovered a flaw in the permission checks for use of the ptrace feature. A local user who has the CAP_SYS_PTRACE capability within their own user namespace could use this flaw for privilege escalation if a more privileged process ever enters that user namespace. This affects at least the LXC system.
In addition, this update fixes some regressions in the previous update :
- #808293 A regression in the UDP implementation prevented freeradius and some other applications from receiving data.
- #808602 / #808953
A regression in the USB XHCI driver prevented use of some devices in USB 3 SuperSpeed ports.
- #808973
A fix to the radeon driver interacted with an existing bug to cause a crash at boot when using some AMD/ATI graphics cards.

- CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options data, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call (bnc#992566).
- CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296).
- CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for remote attackers to hijack TCP sessions via a blind in-window attack (bnc#989152).
- CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608).
- CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary (bnc#986365).
- CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the PIT counter values during state restoration, which allowed guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via a zero value, related to the kvm_vm_ioctl_set_pit and kvm_vm_ioctl_set_pit2 functions (bnc#960689).
- CVE-2013-4312: The Linux kernel allowed local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104 bsc#922947 bsc#968014).
The update package also includes non-security fixes. See advisory for details.

| NASL family | Ubuntu Local Security Checks | | NASL id | UBUNTU_USN-2887-1.NASL | | description | It was discovered that a use-after-free vulnerability existed in the AF_UNIX implementation in the Linux kernel. A local attacker could use crafted epoll_ctl calls to cause a denial of service (system crash) or expose sensitive information. (CVE-2013-7446)
It was discovered that the KVM implementation in the Linux kernel did not properly restore the values of the Programmable Interrupt Timer (PIT). A user-assisted attacker in a KVM guest could cause a denial of service in the host (system crash). (CVE-2015-7513)
Sasha Levin discovered that the Reliable Datagram Sockets (RDS) implementation in the Linux kernel had a race condition when checking whether a socket was bound or not. A local attacker could use this to cause a denial of service (system crash). (CVE-2015-7990)
It was discovered that the Btrfs implementation in the Linux kernel incorrectly handled compressed inline extants on truncation. A local attacker could use this to expose sensitive information.
(CVE-2015-8374).
