    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts. CVE-2016-9588 Jim Mattson discovered that the KVM implementation for Intel x86 processors does not properly handle #BP and #OF exceptions in an L2 (nested) virtual machine. A local attacker in an L2 guest VM can take advantage of this flaw to cause a denial of service for the L1 guest VM. CVE-2017-2636 Alexander Popov discovered a race condition flaw in the n_hdlc line discipline that can lead to a double free. A local unprivileged user can take advantage of this flaw for privilege escalation. On systems that do not already have the n_hdlc module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-n_hdlc.conf install n_hdlc false CVE-2017-5669 Gareth Evans reported that privileged users can map memory at address 0 through the shmat() system call. This could make it easier to exploit other kernel security vulnerabilities via a set-UID program. CVE-2017-5986 Alexander Popov reported a race condition in the SCTP implementation that can be used by local users to cause a denial of service (crash). The initial fix for this was incorrect and introduced further security issues (CVE-2017-6353). This update includes a later fix that avoids those. On systems that do not already have the sctp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-sctp.conf install sctp false CVE-2017-6214 Dmitry Vyukov reported a bug in the TCP implementation's handling of urgent data in the splice() system call. This can be used by a remote attacker for denial of service (hang) against applications that read from TCP sockets with splice(). CVE-2017-6345 Andrey Konovalov reported that the LLC type 2 implementation incorrectly assigns socket buffer ownership. This might be usable by a local user to cause a denial of service (memory corruption or crash) or privilege escalation. On systems that do not already have the llc2 module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-llc2.conf install llc2 false CVE-2017-6346 Dmitry Vyukov reported a race condition in the raw packet (af_packet) fanout feature. Local users with the CAP_NET_RAW capability (in any user namespace) can use this for denial of service and possibly for privilege escalation. CVE-2017-6348 Dmitry Vyukov reported that the general queue implementation in the IrDA subsystem does not properly manage multiple locks, possibly allowing local users to cause a denial of service (deadlock) via crafted operations on IrDA devices. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.86-1. For Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1+deb8u2. We recommend that you upgrade your linux packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

CVE-2017-7184: The xfrm_replay_verify_len function in net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size data after an XFRM_MSG_NEWAE update, which allowed local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) by leveraging the CAP_NET_ADMIN capability (bsc#1030573). - CVE-2017-5970: The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a denial of service (system crash) via (1) an application that made crafted system calls or possibly (2) IPv4 traffic with invalid IP options (bsc#1024938). -

CVE-2015-3288: mm/memory.c in the Linux kernel mishandled anonymous pages, which allowed local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero (bsc#979021). - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c (bnc#1028415) - CVE-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212) -
