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 on ILP32 builds to an out-of-bounds read. The vulnerability is reached when a crafted uncompressed deep-tile EXR causes the sample-count table size calculation in OpenEXRCore decoding.c to wrap before unpack_sample_table() iterates over the full attacker-controlled tile dimensions, allowing denial of service. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14.

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 56449320-97c5-11f1-84d7-3c7c3fba4204 advisory.

    Cary Phillips reports:
    [The OpenEXR 3.4.14] release addresses the following security vulnerabilities:

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

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