CVE-2026-86344 1 Redhat 3 Directory Server, Enterprise Linux, Redhat Directory Server 2026-10-09 7.5 High
A flaw was found in 389-ds-base. An unauthenticated remote attacker can send a complete LDAP operation followed by the first bytes of an incomplete LDAPMessage on the same connection, causing the server to hand that connection to a second worker thread before the first worker's result is flushed. The second worker blocks until nsslapd-ioblocktimeout while holding the connection mutex, preventing delivery of the completed operation's result. Repeating this across a small number of connections proportional to the configured worker-thread pool size exhausts the entire pool under default configuration, denying service to all clients (anonymous and authenticated, plaintext and TLS) for as long as the attacker maintains the connections.
CVE-2026-61801 2 Moby, Redhat 2 Sys, Hummingbird 2026-10-09 5.5 Medium
The `github.com/moby/sys/user` package provides Go utilities for parsing and looking up entries in Unix-style user and group database files. Versions before 0.4.1 do not sufficiently limit entries when parsing `/etc/passwd`- or `/etc/group`-style files, allowing an attacker who can supply a specially crafted file to cause excessive memory consumption and potentially terminate the affected process due to an out-of-memory condition. This issue is patched in version 0.4.1. As a workaround, avoid parsing attacker-controlled user or group database files, or validate and limit untrusted input before parsing it.
CVE-2026-106550 1 Mozilla 1 Convict 2026-10-09 7.5 High
Mozilla's Node-convict (version 6.2.2 and later) is vulnerable to a Denial of Service vulnerability caused by incomplete prototype‑pollution protections in config.set(). An attacker controlling the configuration key can write arbitrary properties to constructor.<key>, which walk() resolves to the global Object function. This allows overwriting core JavaScript methods such as Object.assign, leading to persistent process-wide failures and requiring a restart. The issue bypasses existing filters that only block constructor.prototype.* and __proto__.*. Exploitation requires an endpoint that forwards attacker-controlled keys into config.set().

CVE-2026-107227 1 Asynchttpclient Project 1 Async-http-client 2026-10-09 7.5 High
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.2.0 until 3.0.14, WebSocket permessage-deflate decompression is unbounded when compression is enabled. The inbound pipeline aggregates compressed frames before WebSocketClientCompressionHandler inflates them, so webSocketMaxFrameSize and webSocketMaxBufferSize do not bound decompressed output. A malicious WebSocket peer can send a small compressed message that expands to a very large Netty buffer and exhausts JVM heap. This issue is fixed in version 3.0.14.
CVE-2026-95209 1 Gnu 1 Gnutls 2026-10-09 7.5 High
An issue in gnutls v3.8.13 causes legitimate CA certificates to be rejected, leading to a Denial of Service (DoS).
CVE-2026-95184 1 Gnu 1 Gnutls 2026-10-09 7.5 High
Improper certificate validation in gnutls v3.8.13 causes the application to reject legitimate certificates for valid users, leading to a Denial of Service (DoS).

CVE-2021-37137 6 Debian, Netapp, Netty and 3 more 24 Debian Linux, Oncommand Insight, Netty and 21 more 2026-10-08 7.5 High
The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.
CVE-2020-13934 7 Apache, Canonical, Debian and 4 more 17 Tomcat, Ubuntu Linux, Debian Linux and 14 more 2026-10-08 7.5 High
An h2c direct connection to Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M5 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service.
CVE-2018-12122 3 Nodejs, Redhat, Suse 5 Node.js, Rhel Software Collections, Suse Enterprise Storage and 2 more 2026-10-08 7.5 High
Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Slowloris HTTP Denial of Service: An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time.
CVE-2022-33070 2 Fedoraproject, Protobuf-c Project 2 Fedora, Protobuf-c 2026-10-08 5.5 Medium
Protobuf-c v1.4.0 was discovered to contain an invalid arithmetic shift via the function parse_tag_and_wiretype in protobuf-c/protobuf-c.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via unspecified vectors.
CVE-2021-3733 4 Fedoraproject, Netapp, Python and 1 more 21 Extra Packages For Enterprise Linux, Fedora, Hci Compute Node Firmware and 18 more 2026-10-08 6.5 Medium
There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability.
CVE-2021-37714 5 Jsoup, Netapp, Oracle and 2 more 25 Jsoup, Management Services For Element Software And Netapp Hci, Banking Trade Finance and 22 more 2026-10-08 7.5 High
jsoup is a Java library for working with HTML. Those using jsoup versions prior to 1.14.2 to parse untrusted HTML or XML may be vulnerable to DOS attacks. If the parser is run on user supplied input, an attacker may supply content that causes the parser to get stuck (loop indefinitely until cancelled), to complete more slowly than usual, or to throw an unexpected exception. This effect may support a denial of service attack. The issue is patched in version 1.14.2. There are a few available workarounds. Users may rate limit input parsing, limit the size of inputs based on system resources, and/or implement thread watchdogs to cap and timeout parse runtimes.
CVE-2020-14422 5 Fedoraproject, Opensuse, Oracle and 2 more 6 Fedora, Leap, Enterprise Manager Ops Center and 3 more 2026-10-08 5.9 Medium
Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.
