Description

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. The out-of-bounds read is at a 4GB offset, which usually causes Exiv2 to crash. This issue has been patched in version 0.28.8.
