exiftags package contains utilities to parse a specified JPEG file.
Version: 1.01exiftags package contains utilities to parse a specified JPEG file or, by default, its standard input, looking for a JPEG APP1 section containing Exif (Exchangeable Image File) image metadata. The properties contained in these data are then printed to the standard output. Digital cameras typically add Exif data to the image files they produce, containing information about the camera and digitized image.

The program supports a variety of cameras, and includes additional support for a portion of the maker notes for Asahi (Pentax), Canon, Casio, Fuji, Leica, Minolta, Nikon, Olympus, Panasonic, and Sanyo cameras. Currently this program runs under Windows and Unix-like operating systems.
Two included companion utilities, exifcom and exiftime, perform functions on specific tags. exifcom displays and writes the UserComment Exif tag that some cameras include in the image metadata they create. This program is useful for recording caption or location information in the image file itself.
exiftime displays and adjusts the image's Exif date and time tags. Additionally, the utility can list each file in ascending order by date and time, suitable for use in further image processing (e.g., production of a Web catalog) when filename ordering is not useful.

What's New in This Release:
· A couple of security issues related to data offset overflows and infinite loops possible with malformed Exif data were fixed.
· This resolves CVE-2007-6354, CVE-2007-6355, and CVE-2007-6356.
· If you use exiftags code in a Web-facing or otherwise public application, an upgrade is recommended.
· Also, Canon EOS-5D custom function support, support for custom timestamp preferences in exiftime listings, and support for HP-UX were added.
