Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to an error in the "flac_buffer_copy()" function (flac.c). A remote attacker can send a specially crafted FLAC file, trick the victim into opening it, trigger stack-based buffer overflow and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
