Summary

Integer overflow in the exif_data_load_data_entry function in libexif/exif-data.c in Libexif before 0.6.16 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via an image with many EXIF components, which triggers a heap-based buffer overflow.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
