Description
The issue concerns multiple vulnerabilities in the libexif package, which can lead to a disruption of confidentiality, integrity, and availability of protected information. These vulnerabilities can be exploited remotely. Specifically, the
mnote olympus entry get value function in the EXIF Tag Parsing Library allows remote attackers to cause a denial of service (divide-by-zero error) via an image with crafted EXIF tags.Recommendations

For libexif-0.6.21, update to a version later than 0.6.21.
For libexif-devel versions prior to 0.6.21, update to version 0.6.21 or later.
For libexif-devel-0.6.21, update to a version later than 0.6.21.
For libexif-64bit versions prior to 0.6.21, update to version 0.6.21 or later.
For libexif-32bit versions prior to 0.6.21, update to version 0.6.21 or later.
