flac123 local__vcentry_parse_value() buffer overflow
| flac123-vcentryparsevalue-bo (35175) |  High Risk |
Description:
flac123 is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the local__vcentry_parse_value() function. By sending a specially-crafted vorbis comment with an overly long value_length, a remote attacker could overflow a buffer and execute arbitrary code on the system.
