What is rsyslog?

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.

rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

What is Snort 3?

Snort 3.13.2 is a broad bounds-checking sweep across SMB, HTTP and industrial protocol parsers

Snort 3.13.2.0, released 5 November, is a large roll-up that mostly bounds and validates input: SMB header checks, a fix for an SMB inspection bypass via crafted keep-alive lengths, OLE2 VBA heap fixes, MMS and DNP3 length limits, and a heap out-of-bounds write in the Unix transport. It also adds new http_inspect alerts for malformed or oversized headers, file cache control commands, and appid support for MCP inspector verdicts. The 3.13 line requires the Talos LightSPD rules package from 14 September onward because of an API bump in 3.13.0.0.

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.

◆ Current state

rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

◆ Where it's heading

Across 2026 rsyslog has moved from a host syslog daemon toward a container and cloud log shipper, adding inputs for Kubernetes and outputs for AWS services each cycle. Queueing is the other active area.

◆ Prediction

The next scheduled-stable snapshot is due in December on the two-month rhythm; which outputs it adds is unclear from the feed.

Snort 3.13.2 is a broad bounds-checking sweep across SMB, HTTP and industrial protocol parsers

◆ Current state

Snort 3.13.2.0, released 5 November, is a large roll-up that mostly bounds and validates input: SMB header checks, a fix for an SMB inspection bypass via crafted keep-alive lengths, OLE2 VBA heap fixes, MMS and DNP3 length limits, and a heap out-of-bounds write in the Unix transport. It also adds new http_inspect alerts for malformed or oversized headers, file cache control commands, and appid support for MCP inspector verdicts. The 3.13 line requires the Talos LightSPD rules package from 14 September onward because of an API bump in 3.13.0.0.

◆ Where it's heading

Memory safety and input bounding now dominate every release, with feature work limited to new alerts and operator controls. The appid line about MCP inspector verdicts is the one hint that Snort is starting to classify AI agent traffic, though the entry gives no detail.

◆ Prediction

Expect more parser hardening in 3.13.3 and a 3.12.x maintenance release alongside it; whether MCP inspection becomes a documented feature is unclear from these entries.
