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: libexif (0.6.22). (BZ#1841316)
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)
