    Multiple security vulnerabilities have been found in OpenEXR, command-line     tools and a library for the OpenEXR image format. Buffer overflows or     out-of-bound reads could lead to a denial of service (application crash) if     a malformed image file is processed.

    For Debian 10 buster, these problems have been fixed in version     2.2.1-4.1+deb10u2.

    We recommend that you upgrade your openexr packages.

    For the detailed security status of openexr please refer to     its security tracker page at:

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)

This update for openexr fixes the following issues :

Security issues fixed :

  - CVE-2020-16587: Fixed a heap-based buffer overflow in     chunkOffsetReconstruction in ImfMultiPartInputFile.cpp     (bsc#1179879).

  - CVE-2020-16588: Fixed a NULL pointer deference in     generatePreview (bsc#1179879).

  - CVE-2020-16589: Fixed a heap-based buffer overflow in     writeTileData in ImfTiledOutputFile.cpp (bsc#1179879).

This update was imported from the SUSE:SLE-15:Update update project.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4676-1 advisory.

    It was discovered that OpenEXR incorrectly handled certain malformed EXR image files. If a user were     tricked into opening a crafted EXR image file, a remote attacker could cause a denial of service, or     possibly execute arbitrary code.

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