Ubuntu Security Notice 3405-2 - USN-3405-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that a use-after-free vulnerability existed in the POSIX message queue implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
be8ba4251d1774d576a5d0cbdadc62c4Ubuntu Security Notice 3405-1 - It was discovered that a use-after-free vulnerability existed in the POSIX message queue implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Huang Weller discovered that the ext4 filesystem implementation in the Linux kernel mishandled a needs-flushing-before-commit list. A local attacker could use this to expose sensitive information. Various other issues were also addressed.
179b8f597770848ddee280743b07f0a7Red Hat Security Advisory 2017-1916-01 - The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the name service cache daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fix: A stack overflow vulnerability was found in nan* functions that could cause applications, which process long strings with the nan function, to crash or, potentially, execute arbitrary code.
fb9dfc8a0c17eb7425413e38d3339afaRed Hat Security Advisory 2017-1481-01 - The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the name service cache daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fix: A flaw was found in the way memory was being allocated on the stack for user space binaries. If heap and stack memory regions were adjacent to each other, an attacker could use this flaw to jump over the stack guard gap, cause controlled memory corruption on process stack or the adjacent memory region, and thus increase their privileges on the system. This is glibc-side mitigation which blocks processing of LD_LIBRARY_PATH for programs running in secure-execution mode and reduces the number of allocations performed by the processing of LD_AUDIT, LD_PRELOAD, and LD_HWCAP_MASK, making successful exploitation of this issue more difficult.

dec70585733d3d532b738a209e7812a3Cisco Security Advisory - A vulnerability in the Layer 2 Tunneling Protocol (L2TP) parsing function of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to insufficient validation of L2TP packets. An attacker could exploit this vulnerability by sending a crafted L2TP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
8e211358e033468251f63614e5b2fb40Cisco Security Advisory - A vulnerability in the DHCP client implementation of Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability occurs during the parsing of a crafted DHCP packet. An attacker could exploit this vulnerability by sending crafted DHCP packets to an affected device that is configured as a DHCP client. A successful exploit could allow the attacker to cause a reload of an affected device, resulting in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

1ecabbc72c7b60a99fde956929c63e70Cisco Security Advisory - A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between cluster members. The vulnerability is due to the combination of two factors: The failure to restrict the use of CMP-specific Telnet options only to internal, local communications between cluster members and instead accept and process such options over any Telnet connection to an affected device, and The incorrect processing of malformed CMP-specific Telnet options. An attacker could exploit this vulnerability by sending malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device. Cisco will release software updates that address this vulnerability. There are no workarounds that address this vulnerability.
e95dfb301f191a5ec25fd4391f2377a8Cisco Security Response - Several researchers have reported on the use of Smart Install (SMI) protocol messages toward Smart Install clients, also known as integrated branch clients (IBC), allowing an unauthenticated, remote attacker to change the startup-config file and force a reload of the device, upgrade the IOS image on the device, and execute high-privilege CLI commands on switches running Cisco IOS and IOS XE Software. Cisco does not consider this a vulnerability in Cisco IOS, IOS XE, or the Smart Install feature itself but a misuse of the Smart Install protocol that by design does not require authentication.
c96bbaa757e47e6830e465936de741d3Debian Linux Security Advisory 3778-1 - Michal Marek discovered that ruby-archive-tar-minitar, a Ruby library that provides the ability to deal with POSIX tar archive files, is prone to a directory traversal vulnerability. An attacker can take advantage of this flaw to overwrite arbitrary files during archive extraction via a .. (dot dot) in an extracted filename.

c1a88972c2e7188bba733c5fcecbbb8bRed Hat Security Advisory 2016-2573-02 - The glibc packages provide the standard C libraries, POSIX thread libraries, standard math libraries, and the name service cache daemon used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fix: A stack overflow vulnerability was found in _nss_dns_getnetbyname_r. On systems with nsswitch configured to include "networks: dns" with a privileged or network-facing service that would attempt to resolve user-provided network names, an attacker could provide an excessively long network name, resulting in stack corruption and code execution.
