CVE-2020-0184Network attack vector

Remote media-processing hang via malformed HEVC slice

Published Jun 11, 2020 · Updated Aug 4, 2024

Infinite-loop denial of service in Google Cloud Android 10's media framework allows remote attackers to hang media processing via a crafted HEVC file. When a frame's first decoded slice is dependent, the decoder copies a prior slice header that does not exist instead of rejecting the slice, allowing ihevcd_ref_list() to loop indefinitely. No privileges are required, but a user must process the crafted media; the resulting hang interrupts media service availability.
