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 Zeroheight?

Design system documentation making itself the constraint on AI-generated UI

Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.

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.

Z0.0

Design system documentation making itself the constraint on AI-generated UI

◆ Current state

Three releases in February, each recorded twice. An AI Assistant embedded in SSO-protected styleguides lets viewers chat with the guidelines to find tokens and guidance. The same Assistant became available inside Slack and Microsoft Teams via mention. And a Figma-verified connector for Figma Make brings documented design system guidance into AI-powered prototyping.

◆ Where it's heading

zeroheight's problem has always been that documentation nobody opens does not govern anything. All three releases attack that from different sides: bring the docs to where people already are (Slack, Teams), let them be asked instead of read (Assistant), and inject them into the tool that generates UI (Figma Make). The last is the most consequential, because it changes documentation from a reference into an input.

◆ Prediction

Expect connectors for further AI generation surfaces beyond Figma Make, since the Figma Make integration establishes the pattern of design system guidance as generation context rather than as a page someone consults.
