CVE-2023-49356Public exploitNetwork attack vector

Process crash via unbounded gain-value formatting

Published Dec 22, 2023 · Updated Apr 23, 2025

Stack buffer overflow in MP3Gain 1.6.2 allows attackers to crash the process when it writes APEv2 gain metadata from a crafted MP3 file. While processing the proof-of-concept file, WriteMP3GainAPETag performs a 142-byte formatted write into the fixed 100-byte valueString stack buffer. The crash requires MP3Gain to process the crafted file and affects availability, with no reported confidentiality or integrity impact.
