"The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-2701 advisory.

  - A heap-based buffer overflow vulnerability exists in Academy Software Foundation OpenEXR 2.3.0 in
    chunkOffsetReconstruction in ImfMultiPartInputFile.cpp that can cause a denial of service via a crafted
    EXR file. (CVE-2020-16587)

  - A flaw was found in OpenEXR in versions before 3.0.0-beta. A crafted input file supplied by an attacker,
    that is processed by the Dwa decompression functionality of OpenEXR's IlmImf library, could cause a NULL
    pointer dereference. The highest threat from this vulnerability is to system availability.
    (CVE-2021-20296)

  - An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in
    versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.
    (CVE-2021-23215)

  - An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in
    versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR. This
    is a different flaw from CVE-2021-23215. (CVE-2021-26260)

  - There's a flaw in OpenEXR in versions before 3.0.0-beta. A crafted input file that is processed by OpenEXR
    could cause a shift overflow in the FastHufDecoder, potentially leading to problems with application
    availability. (CVE-2021-3474)

  - There is a flaw in OpenEXR in versions before 3.0.0-beta. An attacker who can submit a crafted file to be
    processed by OpenEXR could cause an integer overflow, potentially leading to problems with application
    availability. (CVE-2021-3475)

  - A flaw was found in OpenEXR's B44 uncompression functionality in versions before 3.0.0-beta. An attacker
    who is able to submit a crafted file to OpenEXR could trigger shift overflows, potentially affecting
    application availability. (CVE-2021-3476)

  - There's a flaw in OpenEXR's deep tile sample size calculations in versions before 3.0.0-beta. An attacker
    who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow,
    subsequently leading to an out-of-bounds read. The greatest risk of this flaw is to application
    availability. (CVE-2021-3477)

  - There's a flaw in OpenEXR's scanline input file functionality in versions before 3.0.0-beta. An attacker
    able to submit a crafted file to be processed by OpenEXR could consume excessive system memory. The
    greatest impact of this flaw is to system availability. (CVE-2021-3478)

  - There's a flaw in OpenEXR's Scanline API functionality in versions before 3.0.0-beta. An attacker who is
    able to submit a crafted file to be processed by OpenEXR could trigger excessive consumption of memory,
    resulting in an impact to system availability. (CVE-2021-3479)

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