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

  - OpenEXR provides the specification and reference implementation of the EXR file format, an image storage
    format for the motion picture industry. From version 3.4.0 to before version 3.4.8, a crafted B44 or B44A
    EXR file can cause an out-of-bounds write in any application that decodes it via exr_decoding_run().
    Consequences range from immediate crash (most likely) to corruption of adjacent heap allocations (layout-
    dependent). This issue has been patched in version 3.4.8. (CVE-2026-34544)

The remote Fedora 45 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-abd4c1829d advisory.

    Automatic update for usd-26.03-2.fc45.

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

The version of OpenEXR installed on the remote host is prior to 1.7.1-8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3267 advisory.

    OpenEXR provides the specification and reference implementation of the EXR file format, an image storage     format for the motion picture industry. From version 3.4.0 to before version 3.4.8, a crafted B44 or B44A     EXR file can cause an out-of-bounds write in any application that decodes it via exr_decoding_run().
    Consequences range from immediate crash (most likely) to corruption of adjacent heap allocations (layout-     dependent). This issue has been patched in version 3.4.8. (CVE-2026-34544)

    OpenEXR provides the specification and reference implementation of the EXR file format, an image storage     format for the motion picture industry. From 3.1.0 to before 3.2.7, 3.3.9, and 3.4.9,     internal_exr_undo_piz() advances the working wavelet pointer with signed 32-bit arithmetic. Because nx,     ny, and wcount are int, a crafted EXR file can make this product overflow and wrap. The next channel then     decodes from an incorrect address. The wavelet decode path operates in place, so this yields both out-of-     bounds reads and out-of-bounds writes. This vulnerability is fixed in 3.2.7, 3.3.9, and 3.4.9.
