Description (partial)
Symptom: Some multistring components may not fire due to the match length being miscalculated. This is a rare situation, but can be seen with signatures using the "match length" parameter, which has a counting irregularity. Conditions: Certain patterns and lengths in a TCP stream can stimulate the condition.
