| NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service (stack exhaustion) via an ntpdc relist command, which triggers recursive traversal of the restriction list. |
| Memory leak in net/vmxnet3.c in QEMU allows remote attackers to cause a denial of service (memory consumption). |
| Memory leak in QEMU, when built with a VMWARE VMXNET3 paravirtual NIC emulator support, allows local guest users to cause a denial of service (host memory consumption) by trying to activate the vmxnet3 device repeatedly. |
| The TIFFReadDirEntryArray function in tif_read.c in LibTIFF 4.0.8 mishandles memory allocation for short files, which allows remote attackers to cause a denial of service (allocation failure and application crash) in the TIFFFetchStripThing function in tif_dirread.c during a tiff2pdf invocation. |
| The WritePixelCachePixels function in ImageMagick 7.0.6-6 allows remote attackers to cause a denial of service (CPU consumption) via a crafted file. |
| Memory leak in the NewXMLTree function in magick/xml-tree.c in ImageMagick before 6.9.4-7 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML file. |
| Memory leak in the ReadPSDLayers function in coders/psd.c in ImageMagick before 6.9.6-3 allows remote attackers to cause a denial of service (memory consumption) via a crafted image file. |
| An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages. (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic. |
| Memory leak in hw/watchdog/wdt_i6300esb.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations. |
| Specially crafted packets sent to port 161/udp could cause a denial of service condition. The affected devices must be restarted manually. |
| In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadSUNImage in coders/sun.c, which allows attackers to cause a denial of service. |
| In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadPCXImage in coders/pcx.c, which allows attackers to cause a denial of service. |
| In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadMPCImage in coders/mpc.c, which allows attackers to cause a denial of service. |
| In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadMIFFImage in coders/miff.c, which allows attackers to cause a denial of service. |
| A vulnerability in the TCP state machine of Cisco RF Gateway 1 devices could allow an unauthenticated, remote attacker to prevent an affected device from delivering switched digital video (SDV) or video on demand (VoD) streams, resulting in a denial of service (DoS) condition. The vulnerability is due to a processing error with TCP connections to the affected device. An attacker could exploit this vulnerability by establishing a large number of TCP connections to an affected device and not actively closing those TCP connections. A successful exploit could allow the attacker to prevent the affected device from delivering SDV or VoD streams to set-top boxes. Cisco Bug IDs: CSCvf19887. |
| A vulnerability in Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient limitations on the number of connections that can be made to the affected software. An attacker could exploit this vulnerability by opening multiple connections to the server and exhausting server resources. A successful exploit could cause the server to reload, resulting in a DoS condition. Cisco Bug IDs: CSCvf41006. |
| The ReadMATImage function in coders/mat.c in ImageMagick through 6.9.9-3 and 7.x through 7.0.6-3 has memory leaks involving the quantum_info and clone_info data structures. |
| A stack-consumption vulnerability was found in libqpdf in QPDF 6.0.0, which allows attackers to cause a denial of service via a crafted file, related to the PointerHolder function in PointerHolder.hh, aka an "infinite loop." |
| The __decode_dotted function in libc/inet/resolv.c in uClibc-ng before 1.0.12 allows remote DNS servers to cause a denial of service (infinite loop) via vectors involving compressed items in a reply. |
| The __read_etc_hosts_r function in libc/inet/resolv.c in uClibc-ng before 1.0.12 allows remote DNS servers to cause a denial of service (infinite loop) via a crafted packet. |
