How to fix?

Upgrade Debian:9 libexif to version 0.6.21-2+deb9u5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libexif package and not the libexif package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

In exif_entry_get_value of exif-entry.c, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution if a third party app used this library to process remote image data with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.1 Android-9 Android-10 Android-11 Android-8.0Android ID: A-159625731
