In opencv/modules/imgcodecs/src/utils.cpp, functions FillUniColor and FillUniGray do not check the input length, which can lead to integer overflow. If the image is from remote, may lead to remote code execution or denial of service. This affects Opencv 3.3 and earlier.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In opencv/modules/imgcodecs/src/utils.cpp, functions FillUniColor and FillUniGray do not check the input     length, which can lead to integer overflow. If the image is from remote, may lead to remote code execution     or denial of service. This affects Opencv 3.3 and earlier. (CVE-2017-1000450)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2799 advisory.

    Several security vulnerabilities have been discovered in OpenCV, the Open Computer Vision Library. Buffer     overflows, NULL pointer dereferences and out-of-bounds write errors may lead to a denial-of-service or     other unspecified impact. For Debian 9 stretch, these problems have been fixed in version     2.4.9.1+dfsg1-2+deb9u1. We recommend that you upgrade your opencv packages. For the detailed security     status of opencv please refer to its security tracker page at: https://security-     tracker.debian.org/tracker/opencv Further information about Debian LTS security advisories, how to apply     these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

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

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

Early versions of opencv have problems while reading data, which might result in either buffer overflows, out-of bounds errors or integer overflows.

Further assertion errors might happen due to incorrect integer cast.

For Debian 8 'Jessie', these problems have been fixed in version 2.4.9.1+dfsg-1+deb8u2.

We recommend that you upgrade your opencv packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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).
