Описание
OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.4.0 through 3.4.9, 3.3.0 through 3.3.9, and 3.2.0 through 3.2.7, internal_dwa_compressor.h:1722 performs curc->width * curc->height in int32 arithmetic without a (size_t) cast. This is the same overflow pattern fixed in other locations by the recent CVE-2026-34589 batch, but this line was missed. Versions 3.4.10, 3.3.10, and 3.2.8 contain a fix that addresses internal_dwa_compressor.h:1722.
A flaw was found in OpenEXR, an image storage format library. An integer overflow vulnerability exists when processing specially crafted EXR image files. A local user could exploit this by tricking a victim into opening a malicious EXR file. This flaw could lead to memory corruption, potentially allowing for arbitrary code execution or causing a denial of service (DoS) on the affected system.
Отчет
Important: This flaw in OpenEXR is not applicable to Red Hat Enterprise Linux products as the vulnerable code is not present. The vulnerability affects Fedora, where an integer overflow in EXR image processing could lead to arbitrary code execution or denial of service if a local user is tricked into opening a malicious EXR file.
