Vulnerability details
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to heap-based buffer over-read in the flac_buffer_copy function in flac.c in libsndfile. A remote attacker can send a specially crafted audio file, trick the victim into opening it, trigger memory corruption and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
