Handle invalid HTTP traffic
---------------------------
Key: HTTPCORE-285
URL: https://issues.apache.org/jira/browse/HTTPCORE-285
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 4.1.2
Reporter: Steve Jones
Invalid HTTP responses are not handled well and can cause OutOfMemoryError
errors.
Most errors can probably be addressed by limiting the length when reading a
line.
For example:
cat /dev/zero | nc -l 1234 # run a server that spews invalid data
java org.apache.http.examples.client.ClientWithResponseHandler # modified
example to connect to above server
Result:
executing request http://localhost:1234/
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
