  - 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.

The remote Ubuntu 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5620-1 advisory.

  - 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's ImfDeepScanLineInputFile functionality in versions prior to 3.0.5. An attacker     who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds     read. The greatest risk from this flaw is to application availability. (CVE-2021-3598)

  - There's a flaw in OpenEXR's rleUncompress functionality in versions prior to 3.0.5. An attacker who is     able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The     greatest risk from this flaw is to application availability. (CVE-2021-3605)

  - An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits.
    This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with     application stability or lead to other attack paths. (CVE-2021-3933)

  - In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 -     chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the     divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition     which could affect the availability of programs linked with OpenEXR. (CVE-2021-3941)

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