CVE-2007-4974

21
FAUCET Score

CVE-2007-4974 describes a heap-based buffer overflow in the flac_buffer_copy function within libsndfile versions 1.0.17 and earlier, affecting mega_nerd libsndfile. This vulnerability allows remote attackers to execute arbitrary code by providing a specially crafted FLAC file with PCM data where a block's size exceeds the previous block's size. With a CVSS score of 7.5, it poses a high risk due to its network attack vector, low attack complexity, and potential for partial confidentiality, integrity, and availability impact. There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage, suggesting it is not currently a high-profile threat.
