Doc Text:
A flaw was found in Exiv2, a C++ library and command-line utility for managing image metadata. An out-of-bounds read vulnerability exists within the preview component. This flaw can be triggered when an attacker processes a specially crafted image file using Exiv2 with a specific command-line argument, such as '-pp'. Successful exploitation of this vulnerability typically leads to a denial of service (DoS) due to the application crashing.

Description OSIDB Bzimport 2026-03-02 20:02:17 UTC 
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.
