CVE-2019-14017Network attack vector

Heap corruption via malformed MKV Vorbis data

Published Jan 21, 2020 · Updated Aug 5, 2024

Heap buffer overflow in Qualcomm Snapdragon media parsing allows remote attackers to corrupt memory with malformed MKV/Vorbis data. The closed-source parser processes an invalid MKV clip containing malformed Vorbis codec data and writes beyond a heap buffer. No privileges or user interaction are required, but Qualcomm has not disclosed whether the overflow yields code execution, a crash, or another consequence.
