Hi, The following vulnerability was published for exiv2. CVE-2021-29464[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
