wireshark: OpenFlow crash (wnpa-sec-2016-60)

In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the OpenFlow dissector could crash with memory exhaustion, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-openflow_v5.c by ensuring that certain length values were sufficiently large.

w3m: Memory exhaustion due to repeatedly appending '<table>'

An issue was discovered in the Tatsuya Kinoshita w3m fork before 0.5.3-33. w3m allows remote attackers to cause a denial of service (infinite loop and resource consumption) via a crafted HTML page.

IBM MQ Light before 1.0.0.2 allows remote attackers to cause a denial of service (disk consumption) via a crafted byte sequence in authentication data, a different vulnerability than CVE-2015-1956 and CVE-2015-1958.

The TCP stack in 4.3BSD Net/2, as used in FreeBSD 5.4, NetBSD possibly 2.0, and OpenBSD possibly 3.6, does not properly implement the session timer, which allows remote attackers to cause a denial of service (resource consumption) via crafted packets.

The (1) PPP Access Concentrator (PPPAC) and (2) Dial-Up Networking Internet Initiative Japan Inc. SEIL series routers SEIL/x86 Fuji 1.00 through 3.22; SEIL/X1, SEIL/X2, and SEIL/B1 1.00 through 4.62; SEIL/Turbo 1.82 through 2.18; and SEIL/neu 2FE Plus 1.82 through 2.18 allow remote attackers to cause a denial of service (restart) via crafted (a) GRE or (b) MPPE packets.

Algorithmic complexity vulnerability in Cybozu Remote Service Manager through 2.3.0 and 3.x through 3.1.2 allows remote attackers to cause a denial of service (CPU consumption) via vectors that trigger colliding hash-table keys. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-1983.

kernel: xfs: directory hash ordering denial of service

The xfs_da3_fixhashpath function in fs/xfs/xfs_da_btree.c in the xfs implementation in the Linux kernel before 3.14.2 does not properly compare btree hash values, which allows local users to cause a denial of service (filesystem corruption, and OOPS or panic) via operations on directories that have hash collisions, as demonstrated by rmdir operations.

gnome-shell: lockscreen bypass with printscreen key

GNOME Shell 3.14.x before 3.14.1, when the Screen Lock feature is used, does not limit the aggregate memory consumption of all active PrtSc requests, which allows physically proximate attackers to execute arbitrary commands on an unattended workstation by making many PrtSc requests and leveraging a temporary lock outage, and the resulting temporary shell availability, caused by the Linux kernel OOM killer.

openstack-neutron: DoS via maliciously crafted dns_nameservers

OpenStack Neutron before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service (crash) via a crafted dns_nameservers value in the DNS configuration.

dbus: local denial of service via incomplete fix for CVE-2014-3636

D-Bus 1.3.0 through 1.6.x before 1.6.26, 1.8.x before 1.8.10, and 1.9.x before 1.9.2 allows local users to cause a denial of service (prevention of new connections and connection drop) by queuing the maximum number of file descriptors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-3636.1.

iplookup/index.php in Moodle through 2.4.11, 2.5.x before 2.5.9, 2.6.x before 2.6.6, and 2.7.x before 2.7.3 allows remote attackers to cause a denial of service (resource consumption) by triggering the calculation of an estimated latitude and longitude for an IP address.

kernel: net: sctp: NULL pointer dereference in af->from_addr_param on malformed packet

The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk.

kernel: aarch64: copying from /dev/zero causes local DoS

The __clear_user function in arch/arm64/lib/clear_user.S in the Linux kernel before 3.17.4 on the ARM64 platform allows local users to cause a denial of service (system crash) by reading one byte beyond a /dev/zero page boundary.

Use-after-free vulnerability in the CPDF_Parser::IsLinearizedFile function in fpdfapi/fpdf_parser/fpdf_parser_parser.cpp in PDFium, as used in Google Chrome before 39.0.2171.65, allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document.

chromium-browser: Use-after-free in pepper plugins

Use-after-free vulnerability in the Pepper plugins in Google Chrome before 39.0.2171.65 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted Flash content that triggers an attempted PepperMediaDeviceManager access outside of the object's lifetime.

chromium-browser: Use-after-free in blink

Multiple use-after-free vulnerabilities in modules/screen_orientation/ScreenOrientationController.cpp in Blink, as used in Google Chrome before 39.0.2171.65, allow remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger improper handling of a detached frame, related to the (1) lock and (2) unlock methods.

ICU: uninitialized value use in the collation component

The collator implementation in i18n/ucol.cpp in International Components for Unicode (ICU) 52 through SVN revision 293126, as used in Google Chrome before 40.0.2214.91, does not initialize memory for a data structure, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted character sequence.

chromium-browser: uninitialized-value in Fonts

The Fonts implementation in Google Chrome before 40.0.2214.91 does not initialize memory for a data structure, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

openstack-swift: Swift metadata constraints are not correctly enforced

OpenStack Object Storage (Swift) before 2.2.0 allows remote authenticated users to bypass the max_meta_count and other metadata constraints via multiple crafted requests which exceed the limit when combined.

The DHCP implementation in Cisco IOS on Aironet access points does not properly handle error conditions with short leases and unsuccessful lease-renewal attempts, which allows remote attackers to cause a denial of service (device restart) by triggering a transition into a recovery state that was intended to involve a network-interface restart but actually involves a full device restart, aka Bug ID CSCtn16281.
