Multiple buffer overflows have been found in libmusicbrainz, which could lead to a Denial of Service or possibly the execution of arbitrary code.
| Package | Arch | Vulnerable | Unaffected |

libmusicbrainz is a client library used to access MusicBrainz music meta data.
Luigi Auriemma reported a possible buffer overflow in the MBHttp::Download function of lib/http.cpp as well as several possible buffer overflows in lib/rdfparse.c.
A remote attacker could be able to execute arbitrary code or cause Denial of Service by making use of an overly long "Location" header in an HTTP redirect message from a malicious server or a long URL in malicious RDF feeds.
There is no known workaround at this time.
All libmusicbrainz users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/musicbrainz-2.1.4"
