What is ClamAV?

ClamAV's file parsers keep yielding CVEs — and every fix ships twice, to two branches.

ClamAV runs two supported lines, 1.5.x and 1.4.x, and publishes identical patch releases seconds apart whenever a vulnerability lands. The recurring source is the same: file format parsers. The July pair fixed a PESpin unpacker use-after-free and an integer overflow in PE rebuild size calculations; the March pair fixed an HTML parser error-handling crash and a JPEG scanning hang inherited from a Rust image dependency. One of the July issues reaches back to code from 2005.

What is ESPEasy?

One release a year, each one a filesystem or networking rewrite you must plan for.

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

ClamAV vs ESPEasy: editorial side-by-side

0.0

ClamAV's file parsers keep yielding CVEs — and every fix ships twice, to two branches.

◆ Current state

ClamAV runs two supported lines, 1.5.x and 1.4.x, and publishes identical patch releases seconds apart whenever a vulnerability lands. The recurring source is the same: file format parsers. The July pair fixed a PESpin unpacker use-after-free and an integer overflow in PE rebuild size calculations; the March pair fixed an HTML parser error-handling crash and a JPEG scanning hang inherited from a Rust image dependency. One of the July issues reaches back to code from 2005.

◆ Where it's heading

Feature work has effectively paused since 1.5.0 last October, which added OLE2 encryption detection and HTML URI recording in JSON metadata. Everything since is patch traffic. The more consequential trend is the Rust dependency chain: fixing image parsing bugs by upgrading crates has twice forced the minimum Rust compiler version upward, which pushes cost onto distribution packagers rather than end users.

◆ Prediction

Expect the dual-branch CVE pattern to continue at roughly quarterly intervals, with the PE and archive parsers the likeliest source given their history here. Whether a 1.6 line opens is not something these entries indicate — there has been no development release since the 1.5.0 cycle.

One release a year, each one a filesystem or networking rewrite you must plan for.

◆ Current state

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

◆ Where it's heading

The project's pattern is long test cycles followed by a build that changes something foundational — filesystem, networking, MCU support — and asks users to back up settings before upgrading. Between those, only hotfixes appear. Development is heavily concentrated in one maintainer's commit stream, with the rest of the contributor list handling docs, build scripts and individual plugins.

◆ Prediction

Given the cadence, the next build is likely months out and shaped by whatever the current test-build issue accumulates; the newly added MCU families are the obvious place for follow-up plugin and peripheral work.
