Descripción técnica

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From SDK version 1.33.0, SDK log version 0.9.0, and trace version 1.35.0 until version 1.47.0, the AttributeValueLengthLimit and WithAttributeValueLengthLimit truncation paths in sdk/internal/attrnorm, sdk/log/internal/attrnorm, and trace/auto.go do not count valid U+FFFD replacement characters. This is a distinct incomplete-fix defect in the replacement truncation code introduced by the remediation for CVE-2026-81869. Values composed of or dominated by those characters can therefore exceed the configured character and memory bound in span, log-record, and auto-instrumentation trace attributes. Attacker-controlled telemetry attributes can increase retained memory and pipeline pressure, while confidentiality and integrity are not affected. This issue is fixed in version 1.47.0.

CVE-2026-128132—

———AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the WebSocket reader continues parsing frames already received after the receive queue pauses the transport, and empty messages are not counted toward the queue size. With permessage-deflate, one read of compressed frames can add many megabytes of decompressed messages to the receive queue. A remote peer can send many small or compressed messages faster than the application consumes them and cause excessive memory use in a server or client. This issue is fixed in version 3.14.4.3h CVE-2026-128130—

———AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, when the pipelined request queue is full, the pure-Python parser stores the unparsed remainder internally and also returns the same data to its caller. After a handler declines an upgrade request, the caller feeds the remainder back to the parser, causing the buffer to grow with each handled request and dispatching already-handled requests to the application again. The issue affects deployments using AIOHTTP_NO_EXTENSIONS or otherwise running without the standard C-extension wheel, and can cause excessive memory use and repeated request processing. This issue is fixed in version 3.14.4.3h CVE-2026-128129—

———AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, aiohttp buffers all additional connection data received while a request marked for upgrade, such as a WebSocket handshake, is being handled, without a size limit or flow control. A remote attacker can stream data behind an upgrade request to a handler that does not immediately accept or reject the upgrade and cause unbounded memory consumption. This issue is fixed in version 3.14.4.3h CVE-2026-1281287.5 ALT

———AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to 3.14.4, the C WebSocket reader adds a declared frame length to the size of an already buffered partial message using signed 64-bit arithmetic. A length near two to the power of 63 can overflow, allowing the max_msg_size check to pass. A remote peer can send a small non-final fragment followed by an oversized message and cause unbounded memory consumption. The Python WebSocket reader is unaffected. This issue is fixed in version 3.14.4.3h CVE-2026-1280897.5 ALT

———dnspython is a DNS toolkit for Python. Prior to version 2.9.2, the from_text() parser for WKS records does not require the service number to be between 0 and 65535 before using it as a bitmap offset. An attacker-controlled zone file can supply a larger number, causing the service bitmap to grow to an extremely large size through inefficient repeated extension, consuming excessive memory and CPU and potentially terminating the process. Applications are affected only when they parse zone-file text whose record type and rdata are attacker controlled. This issue is fixed in version 2.9.2.5h CVE-2026-104204—

———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to version 1.6.1, there is a server-side denial-of-service issue affecting the Structured View object implementation. This issue has been patched in versions 1.6.1 and 1.7.0.3h
