Summary
Red Hat Security Advisory: libexif security, bug fix, and enhancement update
Notes
Topic
An update for libexif is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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#1841320)
Security Fix(es):
* libexif: out of bounds 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: integer overflow in exif_data_load_data_thumbnail function in exif-data.c (CVE-2020-0181)
* libexif: integer overflow in exif_data_load_data_content function in exif-data.c (CVE-2020-0198)
* 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)
