CVE-2009-3895

Estado: ModificadaMedia (6.8)—

Heap-based buffer overflow in the exif_entry_fix function (aka the tag fixup routine) in libexif/exif-entry.c in libexif 0.6.18 allows remote attackers to cause a denial of service or possibly execute arbitrary code via an invalid EXIF image. NOTE: some of these details are obtained from third party information.
