RHSA-2026:68290
Vulnerability from csaf_redhat - Published: 2026-09-16 15:39 - Updated: 2026-11-13 13:40A flaw was found in the klauspost/compress package. A remote attacker can exploit this vulnerability by supplying a specially crafted compression dictionary with an excessively large repeat value, triggering an integer overflow. When the dictionary is subsequently processed, this overflow leads to out-of-bounds memory access, crashing the application and resulting in a Denial of Service (DoS).

A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. A malicious or compromised AMQP broker can exploit this by advertising an extremely small frame size during connection negotiation. This can lead to excessive fragmentation of client publications, consuming significant CPU resources and potentially causing a Denial of Service (DoS) by stalling the client or its host.
A flaw was found in RabbitMQ amqp091-go. The URI.String function in uri.go concatenates TLS asset path values directly into an AMQPS query string without proper encoding. If an application processes a TLS asset path containing special characters like ampersand or equals delimiters, these can be misinterpreted during URI re-parsing. This vulnerability could allow an attacker to overwrite connection options, potentially corrupting the connection configuration or selecting unintended local cryptographic assets, leading to a compromise of the TLS connection.
A flaw was found in RabbitMQ amqp091-go. The `Channel.Qos` function in `channel.go` incorrectly handles negative integer values for `prefetchCount` and `prefetchSize`, casting them to large unsigned integers. This allows an application that processes untrusted Quality of Service (QoS) configuration to request extremely high message prefetch limits. Consequently, a message broker can deliver a large volume of queued messages, leading to client memory exhaustion and a Denial of Service (DoS) condition.
A flaw was found in RabbitMQ amqp091-go, a Go client for AMQP 0.9.1. This vulnerability allows plaintext credentials to be exposed. After a successful PLAIN authentication handshake, the client retains passwords in an unencrypted format within its connection configuration. Local code with access to the connection object, such as logging or debugging tools, can access these sensitive credentials, leading to information disclosure. The credentials remain exposed for the entire duration of the connection.
A flaw was found in RabbitMQ amqp091-go, a Go AMQP 0.9.1 client. When the client synchronously sends events to application-provided channels, an unbuffered or full listener channel can cause the client's reader to block. This blockage prevents the processing of critical messages and heartbeats, leading to connection stalls, deadlocks, and disconnections. This vulnerability can result in a Denial of Service (DoS) for applications using the affected component.
A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send an extreme declared message body size to a client. This causes the client to attempt an excessively large memory allocation without proper size capping, leading to memory exhaustion and termination of the client process. This vulnerability results in a Denial of Service (DoS).
A flaw was found in RabbitMQ amqp091-go. A malicious or compromised broker can send a specially crafted AMQP (Advanced Message Queuing Protocol) message with a malformed field length. This can cause an integer overflow, leading to a runtime panic in the client process. Consequently, the client process terminates, resulting in a denial of service.
A flaw was found in the OpenTelemetry-Go `BatchingProcessor` component. A remote attacker can exploit this by sending a high volume of log emissions, which can fill the asynchronous export buffer. This causes the processor to enter a tight CPU loop, repeatedly retrying to export logs without proper waiting mechanisms. The consequence is the exhaustion of CPU resources, leading to a degradation or denial of service (DoS) in the affected application.
A flaw was found in the `go-openapi/swag` library's `jsonutils` component. This vulnerability, caused by uncontrolled recursion during ordered JSON (JavaScript Object Notation) parsing and serialization, allows remote unauthenticated attackers to submit deeply nested JSON documents. This can lead to a stack overflow, terminating the process and causing a Denial of Service (DoS) for services that accept OpenAPI specifications.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
