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`.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:1712-1 advisory.

    - CVE-2026-40244: Integer overflow in DWA setupChannelData planarUncRle pointer arithmetic (bsc#1262426).
    - CVE-2026-40250: Integer overflow in DWA decoder outBufferEnd pointer arithmetic (bsc#1262425).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 7b83af27-3a86-11f1-90cd-41d47652b1c2 advisory.

    Cary Phillips reports:
    OpenEXR 3.4.10 is a patch release that addresses the following security vulnerabilities:

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.
