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 Wazuh?

Wazuh hardens its 4.14 line while 5.0 rebuilds how agents talk to the manager.

Wazuh ships 4.14 patch releases roughly every two to three weeks, and almost all of the content is security hardening: path traversal and command injection fixes, input validation in the cluster code, connection deadlines and memory leak fixes. 4.14.10 also added memory limits for oversized rulesets and queue warnings for the vulnerability scanner. In parallel, 5.0.0 reached its second release candidate on October 30.

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.

5.0

Wazuh hardens its 4.14 line while 5.0 rebuilds how agents talk to the manager.

◆ Current state

Wazuh ships 4.14 patch releases roughly every two to three weeks, and almost all of the content is security hardening: path traversal and command injection fixes, input validation in the cluster code, connection deadlines and memory leak fixes. 4.14.10 also added memory limits for oversized rulesets and queue warnings for the vulnerability scanner. In parallel, 5.0.0 reached its second release candidate on October 30.

◆ Where it's heading

5.0 is the real change: agents move to HTTPS for talking to the manager, a new detection engine replaces the 4.x analysis daemon, and every server install becomes a cluster node. The 4.14 branch, meanwhile, reads like a security audit being worked through release by release, which keeps current installs safe while 5.0 settles.

◆ Prediction

More 5.0 release candidates are likely before a final release, and 4.14 patch releases with security fixes should keep coming every few weeks; a 5.0 GA date is not stated in these entries.
