Hi,

The following vulnerability was published for exiv2.

CVE-2021-29623[0]:
| Exiv2 is a C++ library and a command-line utility to read, write,
| delete and modify Exif, IPTC, XMP and ICC image metadata. 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. The
| bug is fixed in version v0.27.4.
