What is ClamAV?

Eight CVEs in one August batch — ClamAV's parser surface is the whole story.

ClamAV runs two supported lines, 1.5.x and 1.4.x, and publishes near-identical patch releases seconds apart whenever vulnerabilities land. The August pair is the largest yet in this window: eight CVEs in 1.5.4, six of them backported to 1.4.6, spanning the ZIP catalogue, GPT partition, PESpin, PDF, Mach-O and XAR parsers. Several reach back a decade or more — the PESpin overflow affects builds from 0.90 onward.

What is Knock?

Knock is hardening for enterprise buyers while its agent takes over the analysis work.

Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

ClamAV vs Knock: editorial side-by-side

Eight CVEs in one August batch — ClamAV's parser surface is the whole story.

◆ Current state

ClamAV runs two supported lines, 1.5.x and 1.4.x, and publishes near-identical patch releases seconds apart whenever vulnerabilities land. The August pair is the largest yet in this window: eight CVEs in 1.5.4, six of them backported to 1.4.6, spanning the ZIP catalogue, GPT partition, PESpin, PDF, Mach-O and XAR parsers. Several reach back a decade or more — the PESpin overflow affects builds from 0.90 onward.

◆ Where it's heading

Feature work has been paused since 1.5.0 last October; everything since is patch traffic against the file format parsers, and the batches are growing rather than shrinking. The August release widens the surface beyond parsing for the first time here, with a clamd STATS thread-safety bug that could disclose process memory or crash the daemon. Reporter credits increasingly come from automated discovery — Atuin, GitHub Security Lab, Trail of Bits — which suggests the find rate tracks the tooling pointed at this codebase, not new code being written.

◆ Prediction

Expect the dual-branch pattern to continue and per-batch CVE counts to stay high while automated fuzzing keeps sweeping the parser surface. These entries give no indication of a 1.6 line opening — there has been no development release since the 1.5.0 cycle.

Knock is hardening for enterprise buyers while its agent takes over the analysis work.

◆ Current state

Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

◆ Where it's heading

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.

◆ Prediction

Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
