  - There is a SEGV in Exiv2::Internal::TiffParserWorker::findPrimaryGroups of tiffimage_int.cpp in Exiv2     0.27-RC3. A crafted input will lead to a remote denial of service attack. (CVE-2018-20097)

  - A PngChunk::parseChunkContent uncontrolled memory allocation in Exiv2 through 0.27.1 allows an attacker to     cause a denial of service (crash due to an std::bad_alloc exception) via a crafted PNG image file.
    (CVE-2019-13112)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata     of image files. A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. The heap overflow     is triggered when Exiv2 is used to write metadata into a crafted image file.

  - 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 v0.27.4 and earlier. The out-of-bounds     read is triggered when Exiv2 is used to read the metadata of 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. The bug is fixed in version v0.27.5. (CVE-2021-37620)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata     of image files. An infinite loop was found in Exiv2 versions v0.27.4 and earlier. The infinite loop is     triggered when Exiv2 is used to print the metadata of 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. Note that this bug is only triggered when printing the image ICC profile, which is a     less frequently used Exiv2 operation that requires an extra command line option (`-p C`). The bug is fixed     in version v0.27.5. (CVE-2021-37621)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata     of image files. An infinite loop was found in Exiv2 versions v0.27.4 and earlier. The infinite loop is     triggered when Exiv2 is used to modify the metadata of 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. Note that this bug is only triggered when deleting the IPTC data, which is a less     frequently used Exiv2 operation that requires an extra command line option (`-d I rm`). The bug is fixed     in version v0.27.5. (CVE-2021-37622, CVE-2021-37623)

  - 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 write was found in Exiv2 version v0.28.0. The vulnerable function,     `BmffImage::brotliUncompress`, is new in v0.28.0, so earlier versions of Exiv2 are _not_ affected. The     out-of-bounds write is triggered when Exiv2 is used to read the metadata of a crafted image file. An     attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim     into running Exiv2 on a crafted image file. This bug is fixed in version v0.28.1. Users are advised to     upgrade. There are no known workarounds for this vulnerability. (CVE-2023-44398)

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

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. A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. The heap overflow     is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially     exploit the vulnerability to gain code execution, 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`. The bug is     fixed in version v0.27.4. (CVE-2021-29457)

  - 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. The bug is fixed in version v0.27.4. (CVE-2021-29458)

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`. The bug is fixed in version v0.27.4. Please see our security policy for     information about Exiv2 security. (CVE-2021-29473)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-29457. Reason: This candidate is a     duplicate of CVE-2021-29457. Notes: All CVE users should reference CVE-2021-29457 instead of this     candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2021-31291)

  - An integer overflow in CrwMap::encode0x1810 of Exiv2 0.27.3 allows attackers to trigger a heap-based     buffer overflow and cause a denial of service (DOS) via crafted metadata. (CVE-2021-31292)

  - 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. The bug is fixed in version v0.27.4. 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 `rm`. (CVE-2021-32617)
