             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: Stack overflow (use '-Xss921k' to reproduce)

at org.apache.felix.utils.json.JSONParser.parseValue(JSONParser.java:124)

Caused by: java.lang.StackOverflowError at java.base/java.lang.String.trim(String.java:2681)

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?
