    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.

The remote host is affected by the vulnerability described in GLSA-202210-31 (OpenEXR: Multiple Vulnerabilities)

  - A flaw was found in OpenEXR's hufDecode functionality. This flaw allows an attacker who can pass a crafted     file to be processed by OpenEXR, to trigger an undefined right shift error. The highest threat from this     vulnerability is to system availability. (CVE-2021-20304)

  - A heap-buffer overflow was found in the copyIntoFrameBuffer function of OpenEXR in versions before 3.0.1.
    An attacker could use this flaw to execute arbitrary code with the permissions of the user running the     application compiled against OpenEXR. (CVE-2021-23169)

  - 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)

  - OpenEXR 3.1.x before 3.1.4 has a heap-based buffer overflow in Imf_3_1::LineCompositeTask::execute (called     from IlmThread_3_1::NullThreadPoolProvider::addTask and IlmThread_3_1::ThreadPool::addGlobalTask). NOTE:
    db217f2 may be inapplicable. (CVE-2021-45942)
