Doc Text:	A flaw was found in OpenEXR, a widely used image format in the motion picture industry. When processing a specially crafted EXR image file, an attacker could trigger an application crash. This occurs because the software attempts to access an empty list of image views when a specific header attribute is empty, leading to a Denial of Service (DoS) for the application.	Story Points:	---

Description OSIDB Bzimport 2026-08-25 18:32:30 UTC

OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. OpenEXR versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13 are vulnerable to crashing. This occurs when Imf::GetChannelsInMultiPartFile() processes a crafted EXR with an empty multiView header attribute and Imf::viewFromChannelName() indexes the empty vector for a dotless channel name. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.
