CVE-2022-24599Public exploitNetwork attack vector

Address disclosure via unterminated copyright metadata

Published Feb 22, 2022 · Updated Nov 3, 2025

Information disclosure in Audio File Library 0.3.6 allows attackers to expose heap or libc addresses through a crafted audio file. In printinfo.c, copyrightstring allocates an exact-size buffer for file-supplied copyright metadata, and printfileinfo passes it to printf's %s conversion without adding a terminating null byte. The file must be processed by a caller such as sfinfo or sfconvert; demonstrated output is limited to heap and shared-library address disclosure.
