OpenEXR 3.4.14 contains a NULL Pointer Dereference in the C++ attribute parsing path. A specially crafted EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer to memcpy() without validating the zero-size condition, resulting in undefined behavior and process termination, leading to denial of service.

The remote SUSE Linux SLES16 / SLES_SAP16 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2026:24012-1 advisory.

    This update for openexr fixes the following issue:

    - CVE-2026-88384: NULL pointer dereference in the C++ attribute parsing path when a specially crafted EXR     file       containing an unknown-type attribute with dataSize set to zero is processed (bsc#1282700).

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

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - OpenEXR 3.4.14 contains a NULL Pointer Dereference in the C++ attribute parsing path. A specially crafted
    EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an
    opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer
    to memcpy() without validating the zero-size condition, resulting in undefined behavior and process
    termination, leading to denial of service. (CVE-2026-88384)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
