A flaw was found in Exiv2 in versions before and including 0.27.4-RC1. Improper input validation of the rawData.size property in Jp2Image::readMetadata() in jp2image.cpp can lead to a heap-based buffer overflow via a crafted JPG image containing malicious EXIF data.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4173 advisory.

  - 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.

A read of uninitialized memory 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 read of uninitialized memory is triggered when Exiv2 is used to read the metadata of a     crafted image file. An attacker could potentially exploit the vulnerability to leak a few bytes of stack     memory, if they can trick the victim into running Exiv2 on a crafted image file.

  - 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 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`).

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-2021-29464)

  - 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.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2750 advisory.

  - In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop     and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial     of service via a crafted file. (CVE-2019-20421)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata     of image files.

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 teams reports :

Multiple vulnerabilities covering buffer overflows, out-of-bounds, read of uninitialized memory and denial of serivce. The heap overflow 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. 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.
