3. Description:

The libexif packages provide a library for extracting extra information
from image files.

The following packages have been upgraded to a later upstream version:

Security Fix(es):

* libexif: out of bound write in exif-data.c (CVE-2019-9278)

* libexif: out of bounds read due to a missing bounds check in
exif_data_save_data_entry function in exif-data.c (CVE-2020-0093)

* libexif: use of uninitialized memory in EXIF Makernote handling can lead
to crashes and use-after-free (CVE-2020-13113)

* libexif: unrestricted size in handling Canon EXIF MakerNote data can lead
to consumption of large amounts of compute time (CVE-2020-13114)

* libexif: out of bounds read due to a missing bounds check in
exif_entry_get_value function in exif-entry.c (CVE-2020-0182)

* libexif: divide-by-zero in exif_entry_get_value function in exif-entry.c
(CVE-2020-12767)
