Background

libexif is a library for parsing, editing and saving Exif metadata from images. exif is a small command line interface for libexif.

Description

There is a bug in exif’s XML output format which can result in a null pointer dereference when outputting crafted JPEG EXIF data.

Impact

Workaround

There is no known workaround at this time.

Resolution

All exif users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-gfx/exif-0.6.22"
