In OpenCV 3.3.1, a heap-based buffer over-read exists in the function cv::HdrDecoder::checkSignature in modules/imgcodecs/src/grfmt_hdr.cpp.

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4818-1 advisory.

    It was discovered that OpenCV did not properly manage certain objects, leading to a divide-by-zero. If a     user were tricked into loading a specially crafted file, a remote attacker could potentially use this     issue to cause a denial of service or possibly execute arbitrary code. (CVE-2019-15939)

    It was discovered that OpenCV did not properly manage certain files, leading to an out of bounds read. If     a user were tricked into loading a specially crafted file, a remote attacker could potentially use this     issue to make OpenCV crash, resulting in a denial of service. This issue was only fixed in Ubuntu 18.04     ESM. (CVE-2019-14491, CVE-2019-14492)

    It was discovered that OpenCV did not properly manage certain XML data, leading to a NULL pointer     dereference. If a user were tricked into loading a specially crafted file, a remote attacker could     potentially use this issue to make OpenCV crash, resulting in a denial of service. This issue was only     fixed in Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. (CVE-2019-14493)

    It was discovered that OpenCV did not properly manage certain files, leading to a heap-based buffer     overflow. If a user were tricked into loading a specially crafted file, a remote attacker could     potentially use this issue to cause a denial of service or possibly execute arbitrary code. This issue     only affected Ubuntu 18.04 ESM. (CVE-2017-18009)

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

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

This update for opencv fixes this security issue :

  - CVE-2017-18009: Prevent heap-based buffer over-read in     the function cv::HdrDecoder::checkSignature     (bsc#1074312).

This update for opencv fixes the following issues :

  - CVE-2018-5268: Fixed a heap-based buffer overflow in     incv::Jpeg2KDecoder::readComponent8u in     modules/imgcodecs/src/grfmt_jpeg2000.cppwhen parsing a     crafted image file. (boo#1075017)

  - CVE-2017-17760: Fixed an buffer overflow in function     cv::PxMDecoder::readData (boo#1074313)

  - CVE-2017-18009: Fixed a heap-based buffer over-read in     function cv::HdrDecoder::checkSignature (boo#1074312)

  - CVE-2017-1000450: Functions FillUniColor and FillUniGray     do not check the input length which could lead to out of     bounds writes and crashes (boo#1074487)

  - CVE-2018-5269: Fixed an assertion failure happens in     cv::RBaseStream::setPos     inmodules/imgcodecs/src/bitstrm.cpp because of an     incorrect integer cast (bsc#1075019).
