CVE-2020-26264 1 Ethereum 1 Go Ethereum 2024-11-21 6.5 Medium
Go Ethereum, or "Geth", is the official Golang implementation of the Ethereum protocol. In Geth before version 1.9.25 a denial-of-service vulnerability can make a LES server crash via malicious GetProofsV2 request from a connected LES client. This vulnerability only concerns users explicitly enabling les server; disabling les prevents the exploit. The vulnerability was patched in version 1.9.25.
CVE-2020-26257 2 Fedoraproject, Matrix 2 Fedora, Synapse 2024-11-21 6.5 Medium
Matrix is an ecosystem for open federated Instant Messaging and VoIP. Synapse is a reference "homeserver" implementation of Matrix. A malicious or poorly-implemented homeserver can inject malformed events into a room by specifying a different room id in the path of a `/send_join`, `/send_leave`, `/invite` or `/exchange_third_party_invite` request. This can lead to a denial of service in which future events will not be correctly sent to other servers over federation. This affects any server which accepts federation requests from untrusted servers. The Matrix Synapse reference implementation before version 1.23.1 the implementation is vulnerable to this injection attack. Issue is fixed in version 1.23.1. As a workaround homeserver administrators could limit access to the federation API to trusted servers (for example via `federation_domain_whitelist`).
CVE-2020-26256 1 C2fo 1 Fast-csv 2024-11-21 5.7 Medium
Fast-csv is an npm package for parsing and formatting CSVs or any other delimited value file in node. In fast-cvs before version 4.3.6 there is a possible ReDoS vulnerability (Regular Expression Denial of Service) when using ignoreEmpty option when parsing. This has been patched in `v4.3.6` You will only be affected by this if you use the `ignoreEmpty` parsing option. If you do use this option it is recommended that you upgrade to the latest version `v4.3.6` This vulnerability was found using a CodeQL query which identified `EMPTY_ROW_REGEXP` regular expression as vulnerable.
CVE-2020-26164 2 Kde, Opensuse 3 Kdeconnect, Backports Sle, Leap 2024-11-21 5.5 Medium
In kdeconnect-kde (aka KDE Connect) before 20.08.2, an attacker on the local network could send crafted packets that trigger use of large amounts of CPU, memory, or network connection slots, aka a Denial of Service attack.
CVE-2020-26070 1 Cisco 12 Asr 9000v, Asr 9001, Asr 9006 and 9 more 2024-11-21 8.6 High
A vulnerability in the ingress packet processing function of Cisco IOS XR Software for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper resource allocation when an affected device processes network traffic in software switching mode (punted). An attacker could exploit this vulnerability by sending specific streams of Layer 2 or Layer 3 protocol data units (PDUs) to an affected device. A successful exploit could cause the affected device to run out of buffer resources, which could make the device unable to process or forward traffic, resulting in a DoS condition. The device would need to be restarted to regain functionality.

CVE-2020-25644 2 Netapp, Redhat 12 Oncommand Insight, Oncommand Workflow Automation, Service Level Manager and 9 more 2024-11-21 7.5 High
A memory leak flaw was found in WildFly OpenSSL in versions prior to 1.1.3.Final, where it removes an HTTP session. It may allow the attacker to cause OOM leading to a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-25630 1 Moodle 1 Moodle 2024-11-21 7.5 High
A vulnerability was found in Moodle where the decompressed size of zip files was not checked against available user quota before unzipping them, which could lead to a denial of service risk. This affects versions 3.9 to 3.9.1, 3.8 to 3.8.4, 3.7 to 3.7.7, 3.5 to 3.5.13 and earlier unsupported versions. Fixed in 3.9.2, 3.8.5, 3.7.8 and 3.5.14.
CVE-2020-25601 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 5.5 Medium
An issue was discovered in Xen through 4.14.x. There is a lack of preemption in evtchn_reset() / evtchn_destroy(). In particular, the FIFO event channel model allows guests to have a large number of event channels active at a time. Closing all of these (when resetting all event channels or when cleaning up after the guest) may take extended periods of time. So far, there was no arrangement for preemption at suitable intervals, allowing a CPU to spend an almost unbounded amount of time in the processing of these operations. Malicious or buggy guest kernels can mount a Denial of Service (DoS) attack affecting the entire system. All Xen versions are vulnerable in principle. Whether versions 4.3 and older are vulnerable depends on underlying hardware characteristics.
CVE-2020-25340 1 Nfstream 1 Nfstream 2024-11-21 5.5 Medium
An issue was discovered in NFStream 5.2.0. Because some allocated modules are not correctly freed, if the nfstream object is directly destroyed without being used after it is created, it will cause a memory leak that may result in a local denial of service (DoS).
