An issue was discovered in certain Apple products. iOS before 10.3.3 is affected. watchOS before 3.2.3 is affected. The issue involves the "Messages" component. It allows remote attackers to cause a denial of service (memory consumption and application crash).

An issue was discovered in certain Apple products. iOS before 11 is affected. macOS before 10.13 is affected. tvOS before 11 is affected. watchOS before 4 is affected. The issue involves the "libc" component. It allows remote attackers to cause a denial of service (resource consumption) via a crafted string that is mishandled by the glob function.

An issue was discovered in certain Apple products. macOS before 10.13.1 is affected. The issue involves the "Quick Look" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory consumption) via a crafted Office document.

The inet module in FreeBSD 10.2x before 10.2-PRERELEASE, 10.2-BETA2-p2, 10.2-RC1-p1, 10.1x before 10.1-RELEASE-p16, 9.x before 9.3-STABLE, 9.3-RELEASE-p21, and 8.x before 8.4-STABLE, 8.4-RELEASE-p35 on systems with VNET enabled and at least 16 VNET instances allows remote attackers to cause a denial of service (mbuf consumption) via multiple concurrent TCP connections.

Sandstorm Cap'n Proto before 0.4.1.1 and 0.5.x before 0.5.1.1 allows remote peers to cause a denial of service (CPU and possibly general resource consumption) via a list with a large number of elements.

The implementation of the OSPF protocol in VMware NSX-V Edge 6.2.x prior to 6.2.8 and NSX-V Edge 6.3.x prior to 6.3.3 doesn't correctly handle the link-state advertisement (LSA). A rogue LSA may exploit this issue resulting in continuous sending of LSAs between two routers eventually going in loop or loss of connectivity.

A vulnerability in the detection engine reassembly of Secure Sockets Layer (SSL) packets for Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition because the Snort process consumes a high level of CPU resources. Affected Products: This vulnerability affects Cisco Firepower System Software running software releases 6.0.0, 6.1.0, 6.2.0, or 6.2.1 when the device is configured with an SSL policy that has at least one rule specifying traffic decryption. More Information: CSCvc58563. Known Affected Releases: 6.0.0 6.1.0 6.2.0 6.2.1.

A vulnerability in the Layer 2 Tunneling Protocol (L2TP) parsing function of Cisco IOS (12.0 through 12.4 and 15.0 through 15.6) and Cisco IOS XE (3.1 through 3.18) 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. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS or Cisco IOS XE Software if the L2TP feature is enabled for the device and the device is configured as an L2TP Version 2 (L2TPv2) or L2TP Version 3 (L2TPv3) endpoint. By default, the L2TP feature is not enabled. Cisco Bug IDs: CSCuy82078.

A vulnerability in the web user interface of Cisco IOS XE 3.1 through 3.17 could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to insufficient resource handling by the affected software when the web user interface is under a high load. An attacker could exploit this vulnerability by sending a high number of requests to the web user interface of the affected software. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. To exploit this vulnerability, the attacker must have access to the management interface of the affected software, which is typically connected to a restricted management network. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS XE Software, if the web user interface of the software is enabled. By default, the web user interface is not enabled. Cisco Bug IDs: CSCup70353.

Sandstorm Cap'n Proto before 0.4.1.1 and 0.5.x before 0.5.1.2, when an application invokes the totalSize method on an object reader, allows remote peers to cause a denial of service (CPU consumption) via a crafted small message, which triggers a "tight" for loop. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-2312.

openhpi: world writable /var/lib/openhpi directory

openhpi/Makefile.am in OpenHPI before 3.6.0 uses world-writable permissions for /var/lib/openhpi directory, which allows local users, when quotas are not properly setup, to fill the filesystem hosting /var/lib and cause a denial of service (disk consumption).

xml: xerces-c hash table collisions CPU usage DoS (oCERT-2011-003)

Apache Xerces-C++ allows remote attackers to cause a denial of service (CPU consumption) via a crafted message sent to an XML service that causes hash table collisions.

A vulnerability in the TCP normalizer of Cisco Adaptive Security Appliance (ASA) Software (8.0 through 8.7 and 9.0 through 9.6) and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause Cisco ASA and FTD to drop any further incoming traffic on all interfaces, resulting in a denial of service (DoS) condition. The vulnerability is due to improper limitation of the global out-of-order TCP queue for specific block sizes. An attacker could exploit this vulnerability by sending a large number of unique permitted TCP connections with out-of-order segments. An exploit could allow the attacker to exhaust available blocks in the global out-of-order TCP queue, causing the dropping of any further incoming traffic on all interfaces and resulting in a DoS condition. Cisco Bug IDs: CSCvb46321.

An exploitable Denial of Service vulnerability exists in the API daemon of Circle with Disney running firmware 2.0.1. A large amount of simultaneous TCP connections causes the APID daemon to repeatedly fork, causing the daemon to run out of memory and trigger a device reboot. An attacker needs network connectivity to the device to trigger this vulnerability.

An exploitable vulnerability exists in the user photo update functionality of Circle with Disney running firmware 2.0.1. A repeated set of specially crafted API calls can cause the device to corrupt essential memory, resulting in a bricked device. An attacker needs network connectivity to the device to trigger this vulnerability.

An issue was discovered in certain Apple products. macOS before 10.12.5 is affected. The issue involves the "Security" component. It allows attackers to conduct sandbox-escape attacks or cause a denial of service (resource consumption) via a crafted app.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. tvOS before 10.2 is affected. watchOS before 3.2 is affected. The issue involves the "CoreText" component. It allows remote attackers to cause a denial of service (resource consumption) via a crafted text message.

xml: xerces-j2 hash table collisions CPU usage DoS (oCERT-2011-003)

Apache Xerces2 Java Parser before 2.12.0 allows remote attackers to cause a denial of service (CPU consumption) via a crafted message to an XML service, which triggers hash table collisions.

openstack-nova: Nova FilterScheduler doubles resource allocations during rebuild with new image

An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This regression was introduced with the fix for OSSA-2017-005 (CVE-2017-16239); however, only Nova stable/pike or later deployments with that fix applied and relying on the default FilterScheduler are affected.

binutils: Excessive memory allocation in the dump_relocs_in_section function

The dump_relocs_in_section function in objdump.c in GNU Binutils 2.29.1 does not check for reloc count integer overflows, which allows remote attackers to cause a denial of service (excessive memory allocation, or heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PE file.
