---------------------------------------
Summary: Potential Integer Overflow
Key: APEXMALHAR-2551
URL: https://issues.apache.org/jira/browse/APEXMALHAR-2551
Project: Apache Apex Malhar
Issue Type: Bug
Affects Versions: 3.8.0
Reporter: songwanging
Priority: Minor
Our tool DeepTect has detected a potential integer overflow:
Path:
apex-malhar/library/src/main/java/com/datatorrent/lib/io/fs/Synchronizer.java
{code:java}
long bytesRemainingToRead = length;
int bytesToread = Math.min(BUFFER_SIZE, (int)bytesRemainingToRead);
{code}
In the above code snippet, "bytesRemainingToRead " is a long variable, if it is
super large, directly casting "bytesRemainingToRead" into integer will
definitely lead to a potential integer overflow.
