CVE-2020-15783 1 Siemens 24 Simatic S7-300 Cpu 312, Simatic S7-300 Cpu 312 Firmware, Simatic S7-300 Cpu 314 and 21 more 2024-11-21 7.8 HIGH 7.5 HIGH
A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC TDC CPU555 (All versions), SINUMERIK 840D sl (All versions). Sending multiple specially crafted packets to the affected devices could cause a Denial-of-Service on port 102. A cold restart is required to recover the service.
CVE-2020-15565 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 6.1 MEDIUM 8.8 HIGH
An issue was discovered in Xen through 4.13.x, allowing x86 Intel HVM guest OS users to cause a host OS denial of service or possibly gain privileges because of insufficient cache write-back under VT-d. When page tables are shared between IOMMU and CPU, changes to them require flushing of both TLBs. Furthermore, IOMMUs may be non-coherent, and hence prior to flushing IOMMU TLBs, a CPU cache also needs writing back to memory after changes were made. Such writing back of cached data was missing in particular when splitting large page mappings into smaller granularity ones. A malicious guest may be able to retain read/write DMA access to frames returned to Xen's free pool, and later reused for another purpose. Host crashes (leading to a Denial of Service) and privilege escalation cannot be ruled out. Xen versions from at least 3.2 onwards are affected. Only x86 Intel systems are affected. x86 AMD as well as Arm systems are not affected. Only x86 HVM guests using hardware assisted paging (HAP), having a passed through PCI device assigned, and having page table sharing enabled can leverage the vulnerability. Note that page table sharing will be enabled (by default) only if Xen considers IOMMU and CPU large page size support compatible.
CVE-2020-15166 3 Debian, Fedoraproject, Zeromq 3 Debian Linux, Fedora, Libzmq 2024-11-21 5.0 MEDIUM 7.5 HIGH
In ZeroMQ before version 4.3.3, there is a denial-of-service vulnerability. Users with TCP transport public endpoints, even with CURVE/ZAP enabled, are impacted. If a raw TCP socket is opened and connected to an endpoint that is fully configured with CURVE/ZAP, legitimate clients will not be able to exchange any message. Handshakes complete successfully, and messages are delivered to the library, but the server application never receives them. This is patched in version 4.3.3.

Softing Industrial Automation all versions prior to the latest build of version 4.47.0, The affected product is vulnerable to uncontrolled resource consumption, which may allow an attacker to cause a denial-of-service condition.
CVE-2020-14297 1 Redhat 6 Amq, Jboss-ejb-client, Jboss Enterprise Application Platform Continuous Delivery and 3 more 2024-11-21 4.0 MEDIUM 6.5 MEDIUM
A flaw was discovered in Wildfly's EJB Client as shipped with Red Hat JBoss EAP 7, where some specific EJB transaction objects may get accumulated over the time and can cause services to slow down and eventaully unavailable. An attacker can take advantage and cause denial of service attack and make services unavailable.
CVE-2020-14190 1 Atlassian 2 Crucible, Fisheye 2024-11-21 5.0 MEDIUM 7.5 HIGH
Affected versions of Atlassian Fisheye/Crucible allow remote attackers to achieve Regex Denial of Service via user-supplied regex in EyeQL. The affected versions are before version 4.8.4.
CVE-2020-14152 2 Debian, Ijg 2 Debian Linux, Libjpeg 2024-11-21 5.8 MEDIUM 7.1 HIGH
In IJG JPEG (aka libjpeg) before 9d, jpeg_mem_available() in jmemnobs.c in djpeg does not honor the max_memory_to_use setting, possibly causing excessive memory consumption.
CVE-2020-13949 2 Apache, Oracle 4 Hive, Thrift, Communications Cloud Native Core Network Slice Selection Function and 1 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
In Apache Thrift 0.9.3 to 0.13.0, malicious RPC clients could send short messages which would result in a large memory allocation, potentially leading to denial of service.
CVE-2020-13849 1 Mqtt 1 Mqtt 2024-11-21 5.0 MEDIUM 7.5 HIGH
The MQTT protocol 3.1.1 requires a server to set a timeout value of 1.5 times the Keep-Alive value specified by a client, which allows remote attackers to cause a denial of service (loss of the ability to establish new connections), as demonstrated by SlowITe.
