CVE-2020-0093

Local information disclosure via unchecked EXIF copy

Published May 14, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Android 8.0, 8.1, 9, and 10 allows local users to disclose memory contents through a crafted media file. The exif_data_save_data_entry function in libexif/exif-data.c copies a requested byte count without ensuring that the source buffer contains that many bytes. Exploitation requires user interaction with crafted media, and the resulting impact is limited to local information disclosure.
