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 werf?

Three release channels at once as werf 3 takes shape beside a still-shipping 2.75.

werf publishes into parallel channels simultaneously — v2.75.3 tagged beta, ea and stable landed the same minute as v2.75.4 for alpha, while the v3 line runs separately through 3.0.2, a 3.0.0 alpha and a 3.1.0 dev build. The 2.x entries are corrective: buildah pull retries and serialisation, a stapel service script made executable regardless of umask, host cleanup no longer wiping other werf versions' git cache. The v3 entries carry the actual features.

ClamAV vs werf: editorial side-by-side

ClamAV

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.

5.0

Three release channels at once as werf 3 takes shape beside a still-shipping 2.75.

◆ Current state

werf publishes into parallel channels simultaneously — v2.75.3 tagged beta, ea and stable landed the same minute as v2.75.4 for alpha, while the v3 line runs separately through 3.0.2, a 3.0.0 alpha and a 3.1.0 dev build. The 2.x entries are corrective: buildah pull retries and serialisation, a stapel service script made executable regardless of umask, host cleanup no longer wiping other werf versions' git cache. The v3 entries carry the actual features.

◆ Where it's heading

The v3 work is about making builds predictable and inspectable: embedded kubeconform schemas, a per-project meta-repo safeguard with a migration path, additional patches files with the defaults disableable, and repo-built scratch images made readable by dive. Meanwhile v3 alphas are restoring flags that v3 had dropped, which suggests the major is being trimmed and then walked back based on review. Dockerfile fidelity — COPY --parents, COPY/ADD --exclude in staged builds — is a recurring thread across both lines.

◆ Prediction

Expect the 2.75 line to keep taking build-backend fixes while v3 stabilises, with more v2 flags restored in v3 alphas as review findings land before the major reaches a stable channel.
