JPEG pictures with certain EXIF data, like those from SONY, Nikon
or Canon digital cameras.
Obtained from libexif CVS, exif-data.c, rev. 1.68, via FreeBSD.
Noted by Leonard Schmidt on tech-pkg.
"Matthias Clasen has reported a vulnerability in libexif, which can be
exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an infinite recursion in the
"exif_data_load_data_content()" function and can be exploited to
cause a stack overflow when parsing a specially crafted image.
Successful exploitation may crash an application linked against the
vulnerable library."
Bump PKGREVISION. Patch from:
http://sourceforge.net/tracker/index.php?func=detail&aid=1196787&group_id=12272&atid=112272
* Final fix of Ubuntu Security Notice USN-91-1 (CAN-2005-0664)
https://bugzilla.ubuntulinux.org/show_bug.cgi?id=7152
* Updated build system with cross compile capabilities
* Small fixes:
Fix tag order, use even offsets, improve Nikon&Olympus mnote tags.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
* libexif/exif-data.h: Introduce an array of ExifContents. This
doesn't break binary compatibility, but it breaks compilation.
Do something like "%s/->ifd_0/->ifd[EXIF_IFD_0]" in your source
code to make it compile again.
* libexif/configure.in: Introduce proper versionning.
* libexif: There's only one ByteOrder per ExifData.
* libexif/libexif-entry.c: More tags implemented in
(exif_entry_get_value).
Most digital cameras produce EXIF files, which are JPEG files with extra
tags that contain information about the image. The EXIF library allows you
to parse an EXIF file and read the data from those tags.
