CyberRota Analysis
AI-GeneratedOpenEXR versions 3.4.0 through 3.4.13 are vulnerable to a denial of service attack caused by a crafted HTJ2K-compressed EXR file that can lead to a stack out-of-bounds write during decoding. This vulnerability arises from improper validation of tile-grid geometry, allowing attackers to exploit the decoder and crash the application. Organizations using OpenEXR in their workflows, particularly in the motion picture industry, should prioritize upgrading to version 3.4.14 to mitigate this risk.

Original NVD Description
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. From version 3.4.0 through 3.4.13, a crafted HTJ2K-compressed EXR can crash OpenEXR during normal decode. An HTJ2K-compressed EXR whose JPEG 2000 SIZ fields place the first tile outside the visible image can reach invalid tile and codeblock geometry in the vendored OpenJPH AVX2 decoder, causing a stack out-of-bounds write and denial of service. OpenEXR's HTJ2K path validates the decoded codestream dimensions against the EXR chunk size, but it does not reject SIZ image-offset/tile-grid geometry where the first tile does not intersect the image. This issue is fixed in version 3.4.14.
