The Nokia 6131 Near Field Communication (NFC) phone with 05.12 firmware allows remote attackers to cause a denial of service (device crash) via (1) a large value in the payload length field in an NDEF record, or a certain length for a (2) tel: or (3) sms: NDEF URI.

The Nokia 6131 Near Field Communication (NFC) phone with 05.12 firmware automatically installs software upon completing the download of a JAR file, which makes it easier for remote attackers to execute arbitrary code via a crafted URI record in an NDEF tag.

The SmartPoster implementation on the Nokia 6131 Near Field Communication (NFC) phone with 05.12 firmware does not properly display the URI record when the Title record contains a certain combination of space, CR (aka \r), and . (dot) characters, which allows remote attackers to trick a user into loading an arbitrary URI via a crafted NDEF tag, as demonstrated by (1) an http: URI for a malicious web site, (2) a tel: URI for a premium-rate telephone number, and (3) an sms: URI that triggers purchase of a ringtone.
