According to the versions of the exiv2 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Exiv2 is a command-line utility and C++ library for     reading, writing, deleting, and modifying the metadata     of image files. An out-of-bounds read was found in     Exiv2 versions v0.27.3 and earlier. The out-of-bounds     read is triggered when Exiv2 is used to write metadata     into a crafted image file. An attacker could     potentially exploit the vulnerability to cause a denial     of service by crashing Exiv2, if they can trick the     victim into running Exiv2 on a crafted image file. Note     that this bug is only triggered when writing the     metadata, which is a less frequently used Exiv2     operation than reading the metadata. For example, to     trigger the bug in the Exiv2 command-line application,     you need to add an extra command-line argument such as     insert.(CVE-2021-29458)

  - Exiv2 is a C++ library and a command-line utility to     read, write, delete and modify Exif, IPTC, XMP and ICC     image metadata. An out-of-bounds read was found in     Exiv2 versions v0.27.3 and earlier. Exiv2 is a     command-line utility and C++ library for reading,     writing, deleting, and modifying the metadata of image     files.

An     attacker could potentially exploit the vulnerability to     cause a denial of service by crashing Exiv2, if they     can trick the victim into running Exiv2 on a crafted     image file. Note that this bug is only triggered when     writing the metadata, which is a less frequently used     Exiv2 operation than reading the metadata. For example,     to trigger the bug in the Exiv2 command-line     application, you need to add an extra command-line     argument such as `insert`.(CVE-2021-29473)

  - Exiv2 is a command-line utility and C++ library for     reading, writing, deleting, and modifying the metadata     of image files. An inefficient algorithm (quadratic     complexity) was found in Exiv2 versions v0.27.3 and     earlier. The inefficient algorithm is triggered when     Exiv2 is used to write metadata into a crafted image     file. An attacker could potentially exploit the     vulnerability to cause a denial of service, if they can     trick the victim into running Exiv2 on a crafted image     file.(CVE-2021-32617)

  - Exiv2 0.27.2 allows attackers to trigger a crash in     Exiv2::getULong in types.cpp when called from     Exiv2::Internal::CiffDirectory::readDirectory in     crwimage_int.cpp, because there is no validation of the     relationship of the total size to the offset and     size.(CVE-2019-17402)

  - Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26     allows remote attackers to cause a denial of service     (heap-based buffer over-read) via a crafted image file,     a different vulnerability than     CVE-2018-10999.(CVE-2018-16336)

  - Exiv2::isoSpeed in easyaccess.cpp in Exiv2 v0.27-RC2     allows remote attackers to cause a denial of service     (NULL pointer dereference and application crash) via a     crafted file.(CVE-2018-19607)

  - Exiv2 0.26 has a heap-based buffer overflow in getData     in preview.cpp.(CVE-2018-11531)

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3852-1 advisory.

  - There is a Floating point exception in the Exiv2::ValueType function in Exiv2 0.26 that will lead to a     remote denial of service attack via crafted input. (CVE-2017-11591)

  - There is a reachable assertion in the Internal::TiffReader::visitDirectory function in tiffvisitor.cpp of     Exiv2 0.26 that will lead to a remote denial of service attack via crafted input. (CVE-2017-11683)

  - An Invalid memory address dereference was discovered in Exiv2::StringValueBase::read in value.cpp in Exiv2     0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of     service. (CVE-2017-14859)

  - An Invalid memory address dereference was discovered in Exiv2::DataValue::read in value.cpp in Exiv2 0.26.
    The vulnerability causes a segmentation fault and application crash, which leads to denial of service.
    (CVE-2017-14862)

  - An Invalid memory address dereference was discovered in Exiv2::getULong in types.cpp in Exiv2 0.26. The     vulnerability causes a segmentation fault and application crash, which leads to denial of service.

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

A vulnerability has been discovered in exiv2 (CVE-2018-16336), a C++ library and a command line utility to manage image metadata, resulting in remote denial of service (heap-based buffer over-read/overflow) via a crafted image file.

Additionally, this update includes a minor change to the patch for the CVE-2018-10958/CVE-2018-10999 vulnerability first addressed in DLA 1402-1. The initial patch was overly restrictive and has been adjusted to remove the excessive restriction.

For Debian 8 'Jessie', these problems have been fixed in version 0.24-4.1+deb8u2.

We recommend that you upgrade your exiv2 packages.
