Inspektor Gadget is a set of tools and framework for data collection and system inspection on Kubernetes clusters and Linux hosts using eBPF. Prior to 0.50.1, in a situation where the ring-buffer of a gadget is – incidentally or maliciously – already full, the gadget will silently drop events. The include/gadget/buffer.h file contains definitions for the Buffer API that gadgets can use to, among the other things, transfer data from eBPF programs to userspace. For hosts running a modern enough Linux kernel (>= 5.8), this transfer mechanism is based on ring-buffers. The size of the ring-buffer for the gadgets is hard-coded to 256KB. When a gadget_reserve_buf fails because of insufficient space, the gadget silently cleans up without producing an alert. The lost count reported by the eBPF operator, when using ring-buffers – the modern choice – is hardcoded to zero. The vulnerability can be used by a malicious event source (e.g. a compromised container) to cause a Denial Of Service, forcing the system to drop events coming from other containers (or the same container). This vulnerability is fixed in 0.50.1.Show less

matrix-rust-sdk is an implementation of a Matrix client-server library in Rust. Versions of the matrix-sdk-crypto Rust crate before 0.8.0 lack a dedicated mechanism to notify that a user's cryptographic identity has changed from a verified to an unverified one, which could cause client applications relying on the SDK to overlook such changes. matrix-sdk-crypto 0.8.0 adds a new VerificationLevel::VerificationViolation enum variant which indicates that a previously verified identity has been changed.Show less

DroneScout ds230 Remote ID receiver from BlueMark Innovations is affected by an information loss vulnerability through traffic injection. An attacker can exploit this vulnerability by injecting, on carefully selected channels, high power spoofed Open Drone ID (ODID) messages which force the DroneScout ds230 Remote ID receiver to drop real Remote ID (RID) information and, instead, generate and transmit JSON encoded MQTT messages containing crafted RID information. Consequently, the MQTT broker, typically operated by a system integrator, will have no access to the drones’ real RID information. This issue affects the adjacent channel suppression algorithm present in DroneScout ds230 firmware from version 20211210-1627 through 20230329-1042.Show less

DroneScout ds230 Remote ID receiver from BlueMark Innovations is affected by an information loss vulnerability through traffic injection. An attacker can exploit this vulnerability by injecting, at the right times, spoofed Open Drone ID (ODID) messages which force the DroneScout ds230 Remote ID receiver to drop real Remote ID (RID) information and, instead, generate and transmit JSON encoded MQTT messages containing crafted RID information. Consequently, the MQTT broker, typically operated by a system integrator, will have no access to the drones’ real RID information. This issue affects DroneScout ds230 in default configuration from firmware version 20211210-1627 through 20230329-1042.Show less
