Michael Cooper commented on AVRO-1237:
--------------------------------------
This looks like it made it into 1.7.6 (CHANGELOG.txt), but the "Fix version" wasnt filled in.
So I have updated the "Fix version" field.

> libavro will segfault when decrypting a specially crafted (or corrupted) avro file when the discriminant is out of bounds.
> There is already a check for < 0, but there is no upper bounds check.
> I have attached a patch that checks the bounds.
