Summary: Stack overflow finding found by OSS-Fuzz
Key: FELIX-6592
URL: https://issues.apache.org/jira/browse/FELIX-6592
Project: Felix
Issue Type: Bug
Reporter: Henry Lin
Attachments: 51725-apache-felix-dev-JSONParserFuzzer.zip
Dear Apache Felix Dev developers,
Fuzzing has found a stack overflow in OSS-Fuzz with JVM Fuzzer Jazzer in Apache
Felix Dev. We have reviewed the finding and consider it security-related due to
the potential of a denial of service.
Part of the crash stack trace:
== Java Exception: com.code_intelligence.jazzer.api.FuzzerSecurityIssueLow:

We have included a reproducer zip which contains a README file that describes
how to reproduce the issue.
We would appreciate if you could take a look into the findings. Do you see a
risk that this might be exploited by untrusted input?
