What is OpenEXR?

A second IDManifest flaw lands two weeks after OpenEXR's forty-CVE sweep

OpenEXR's recent history is dominated by security response. On 2026-08-05 three branches were tagged within two minutes — v3.4.14, v3.3.13 and v3.2.11, fixing 15, 15 and 10 CVEs from one fuzzing and audit campaign, all memory corruption reachable by opening a crafted .exr file. Two weeks later v3.4.15 and v3.3.14 fix two further memory-allocation issues, this time confined to the code that decodes the idmanifest attribute, with CVEs requested but not yet assigned. The 3.4 tag also carries a missing Windows export and reduced compiler warnings in example code.

What is thematic?

thematic exists to follow ggplot2 and the IDEs, and that is all it does now.

Every release since the 0.1.1 debut is compatibility work. 0.1.7 accommodates ggplot2 v4.0.0; 0.1.5 absorbs breaking changes in ggplot2 v3.5.0 and restores vdiffr compatibility; 0.1.6 adds basic Positron IDE support and tracks a systemfonts deprecation; 0.1.4 adds the httpgd graphics device, which is what makes the package work in GitHub Codespaces. Earlier fixes cover gganimate, ggiraph, geom_sf overrides and Shiny-runtime Rmd documents.

A second IDManifest flaw lands two weeks after OpenEXR's forty-CVE sweep

◆ Current state

OpenEXR's recent history is dominated by security response. On 2026-08-05 three branches were tagged within two minutes — v3.4.14, v3.3.13 and v3.2.11, fixing 15, 15 and 10 CVEs from one fuzzing and audit campaign, all memory corruption reachable by opening a crafted .exr file. Two weeks later v3.4.15 and v3.3.14 fix two further memory-allocation issues, this time confined to the code that decodes the idmanifest attribute, with CVEs requested but not yet assigned. The 3.4 tag also carries a missing Windows export and reduced compiler warnings in example code.

◆ Where it's heading

The pattern is now established: findings arrive from a continuing fuzzing effort and are patched simultaneously across every supported stream, with the release notes written to tell integrators precisely which code paths are reachable. The narrowing scope is the useful signal — August's first batch spanned the C++ libraries, the command-line tools and the Python bindings, while this one touches only idmanifest decoding and explicitly states other code is unaffected even on files carrying the attribute. Both new tags are release candidates dated ahead of their tagging, and the 3.3 backport reuses the 3.4 note verbatim, down to naming v3.4.15 in its own body.

◆ Prediction

Expect the requested CVEs to be assigned identifiers and the two RCs to be promoted to final tags, with a matching 3.2 backport if the idmanifest code is present in that stream. Further attribute-parser findings are likely while the fuzzing campaign continues.

thematic exists to follow ggplot2 and the IDEs, and that is all it does now.

◆ Current state

Every release since the 0.1.1 debut is compatibility work. 0.1.7 accommodates ggplot2 v4.0.0; 0.1.5 absorbs breaking changes in ggplot2 v3.5.0 and restores vdiffr compatibility; 0.1.6 adds basic Positron IDE support and tracks a systemfonts deprecation; 0.1.4 adds the httpgd graphics device, which is what makes the package work in GitHub Codespaces. Earlier fixes cover gganimate, ggiraph, geom_sf overrides and Shiny-runtime Rmd documents.

◆ Where it's heading

thematic's premise — automatic theming across R's plotting stack — means its maintenance burden is entirely other people's release schedules. The work splits cleanly into keeping up with ggplot2's breaking changes and reaching new rendering surfaces as they appear: httpgd for browser-based sessions, Positron as RStudio's successor. Roughly one release a year, each one reactive.

◆ Prediction

The next release will most likely track another ggplot2 change or add a new IDE or graphics device; that is the only pattern seven releases show.
