Subject [jira] [Created] (AVRO-1237) Avro-C segfaults when union discriminant out of bounds
Date Fri, 01 Feb 2013 05:37:12 GMT
Michael Cooper created AVRO-1237:

             Summary: Avro-C segfaults when union discriminant out of bounds
                 Key: AVRO-1237
                 URL: https://issues.apache.org/jira/browse/AVRO-1237
             Project: Avro
          Issue Type: Bug
          Components: c
         Environment: Avro-C 1.7.2
Ubuntu 12.04 x86_64
            Reporter: Michael Cooper

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.
