Indeo Otter through 1.7.4 mishandles a "</script>" substring in an initial DP payload, which allows remote attackers to cause a denial of service (crash) or possibly have unspecified other impact, as demonstrated by the Plan Editor.

Inedo Otter before 1.7.4 has directory traversal in filesystem-based rafts via vectors involving '/' characters or initial '.' characters, aka OT-181.
