Luigi Auriemma has reported some vulnerabilities in libmusicbrainz, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
1) A boundary error within the MBHttp::Download function in lib/http.cpp can be exploited to cause a buffer overflow via a large "location" field in a HTTP redirection received from a malicious MusicBrainz server.
2) Various boundary errors within rdfparse.c can be exploited to cause buffer overflows via very long URLs included in a malicious RDF feed.
Successful exploitation may allow execution of arbitrary code.
Solution: Do not connect to untrusted MusicBrainz servers.
