AcademySoftwareFoundation.openexr is vulnerable to Denial of Service
55
Medium Risk
This Affects:
AcademySoftwareFoundation.openexrTL;DR
An empty multiView attribute in a crafted EXR file can make viewFromChannelName() crash while resolving channel-to-view mappings. Applications that open untrusted EXR files and exercise multi-view channel naming therefore suffer a denial of service. The fix rejects empty multiView attributes before view resolution.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you open untrusted EXR files that can carry a multiView attribute.
Background info
AcademySoftwareFoundation.openexr is vulnerable to Denial of Service in versions 3.3.0 - 3.3.12 and 3.4.0 - 3.4.13.
How to fix this
Upgrade the AcademySoftwareFoundation.openexr library to the patch version.
