Synopsis

Moderate: libexif security, bug fix, and enhancement update

Type/Severity

Security Advisory: Moderate

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.

Description

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)
