CVE-2018-9353Public exploitNetwork attack vector

Media-service crash via unchecked HEVC slice data

Published Nov 27, 2024 · Updated Nov 29, 2024

Out-of-bounds read in Android 7, 7.1.1, 7.1.2, 8, and 8.1 allows remote attackers to crash the media service via a crafted HEVC file. ihevcd_parse_slice_data in ihevcd_parse_slice.c reads beyond a heap buffer because it fails to bounds-check parsed HEVC slice data. Exploitation requires user interaction with the crafted file; the documented consequence is a media-service crash, not code execution.
