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 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. 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.

  - ** 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)
