--------------------------------------
Summary: Invalid length in StringValue::LeastSmallerString()
Key: IMPALA-12478
URL: https://issues.apache.org/jira/browse/IMPALA-12478
Project: IMPALA
Issue Type: Bug
Components: Backend
Reporter: Daniel Becker
Assignee: Daniel Becker
In StringValue::LeastSmallerString() we don not check if 'len' is 0 before
subtracting 1 from it. The resulting, possibly negative value is later used as
the length of a new string.
See
https://github.com/apache/impala/blob/ae14d78c8f2e8366e67aa8c39f0c02c60862905e/be/src/runtime/string-value.cc#L51
