Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

 - 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:
