The default values for Session.config.KeepAliveInterval and Session.config.ConnectionWriteTimeout of 30s and 10s create the possibility for timed out writes that most aren't handling in their readers. Calls to Stream.Read on one side of a connection will hang until the underlying Session is closed if the corresponding Stream.Write call on the other side it's waiting for returns with ErrConnectionWriteTimeout. This happens in the case of network congestion between the two sides. If you keep Session.sendCh full (fixed capacity of 64) for ConnectionWriteTimeout, but for less than the KeepAliveInterval + ConnectionWriteTimeout (which would kill the Session), Stream.Write will return ErrConnectionWriteTimeout. The state of the underlying Session or Stream is not modified. When this happens, the other side's Stream.Read call that's waiting for that write will never return because there's no timeout for this edge-case. Since no keep alive timed out, you can continue to use the Session once...

Yet another spinoff of the infamous DDoS botnet is exploiting a known vulnerability in active attacks, while its threat actors are promoting it on Telegram for other attackers to use as well, in a DDoS-as-a-service model.

Cisco Talos’ Vulnerability Research team recently disclosed three vulnerabilities in Observium, three vulnerabilities in Offis, and four vulnerabilities in Whatsup Gold.    These vulnerabilities exist in Observium, a network observation and monitoring system; Offis DCMTK, a collection of libraries and applications implementing DICOM (Digital Imaging and Communications

An issue in the reset password interface of ruoyi v4.8.0 allows attackers with Admin privileges to cause a Denial of Service (DoS) by duplicating the login name of the account.

### Impact The [ContextLines integration](https://docs.sentry.io/platforms/javascript/guides/node/configuration/integrations/contextlines/) uses readable streams to more efficiently use memory when reading files. The ContextLines integration is used to attach source context to outgoing events. The stream was not explicitly closed after use. This could lead to excessive amounts of file handles open on the system and potentially lead to a Denial of Service (DoS). The ContextLines integration is enabled by default in the Node SDK (`@sentry/node`) and SDKs that run in Node.js environments (`@sentry/astro`, `@sentry/aws-serverless`, `@sentry/bun`, `@sentry/google-cloud-serverless`, `@sentry/nestjs`, `@sentry/nextjs`, `@sentry/nuxt`, `@sentry/remix`, `@sentry/solidstart`, `@sentry/sveltekit`). ### Patches Users should upgrade to version `8.49.0` or higher. ### Workarounds To remediate this issue in affected versions without upgrading to version `8.49.0` and above you can disable the Co...

A vulnerability was found in CRI-O. A path traversal issue in the log management functions (UnMountPodLogs and LinkContainerLogs) may allow an attacker with permissions to create and delete Pods to unmount arbitrary host paths, leading to node-level denial of service by unmounting critical system directories.

Threat actors are exploiting an unspecified zero-day vulnerability in Cambium Networks cnPilot routers to deploy a variant of the AISURU botnet called AIRASHI to carry out distributed denial-of-service (DDoS) attacks. According to QiAnXin XLab, the attacks have leveraged the security flaw since June 2024. Additional details about the shortcomings have been withheld to prevent further abuse. Some
