What is Prowler?

Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?

Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

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.

Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?

◆ Current state

Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

◆ Where it's heading

Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.

◆ Prediction

Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.

5.0

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.
