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.

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

        An out-of-bounds read was found in Exiv2. 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-2021-32815

        The assertion         failure 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 modifying 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 `fi`.

    CVE-2021-34334

        An infinite loop 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.

    CVE-2021-37620

        An 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.

    CVE-2021-37621

        An 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`).

    CVE-2021-37622

        An 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`).
