[jira] [Created] (AVRO-1159) Avro-C: read_union_value does not
check discriminant
Lucas Martin-King created AVRO-1159:
---------------------------------------
Summary: Avro-C: read_union_value does not check discriminant
Key: AVRO-1159
URL: https://issues.apache.org/jira/browse/AVRO-1159
Project: Avro
Issue Type: Bug
Components: c
Affects Versions: 1.7.1
Reporter: Lucas Martin-King
Currently read_union_value() in value-read.c does not check if the discriminant it reads is valid in any way.
This can lead to SEGFAULTs after the use of avro_value_set_branch() as read_value() will attempt to read beyond or behind our dataum in memory.
