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 ragg?

R's default raster device is done proving itself and is now just keeping pace.

ragg is the AGG-backed raster device that replaced the base R graphics devices as the default in RStudio and the tidyverse toolchain, and its release stream reads accordingly. The last two years added WebP output, an optimised recording device, saturate composition, and hold-and-flush support requested by Positron; the last two releases are a symbol-font fallback fix and a sanitizer issue. Nothing here is reaching for new territory.

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.

R's default raster device is done proving itself and is now just keeping pace.

◆ Current state

ragg is the AGG-backed raster device that replaced the base R graphics devices as the default in RStudio and the tidyverse toolchain, and its release stream reads accordingly. The last two years added WebP output, an optimised recording device, saturate composition, and hold-and-flush support requested by Positron; the last two releases are a symbol-font fallback fix and a sanitizer issue. Nothing here is reaching for new territory.

◆ Where it's heading

This is a mature default in the maintenance mode that comes with being depended on by everything. The work splits cleanly into three streams: correctness fixes forced by upstream FreeType and compiler changes, small format and API additions contributed from outside, and plumbing to serve whichever IDE is hosting the plot pane. None of the six releases in view changes what ragg is for.

◆ Prediction

Expect the next releases to track the systemfonts variable-font API and further Positron device requirements rather than to add output formats on their own initiative.
