Subject [jira] [Created] (AXIS2C-1597) Memory corruption in axis2_http_transport_utils_process_accept_headers()
Date Fri, 15 Jun 2012 23:59:42 GMT
Ivan Pechorin created AXIS2C-1597:

             Summary: Memory corruption in axis2_http_transport_utils_process_accept_headers()
                 Key: AXIS2C-1597
             Project: Axis2-C
          Issue Type: Bug
          Components: transport/http
    Affects Versions: Current (Nightly)
            Reporter: Ivan Pechorin
            Priority: Critical
         Attachments: axis2-c-accept_record_list.patch

There's an obvious bug/typo in src/core/transport/http/util/http_transport_utils.c in function
First, the "Accept:" header is tokenized into <accept_field_list>.
Then in a loop (iterating over the accept_record_list):
1) each field is parsed into struct axis2_http_accept_record_t
2) the struct should be added into a list of records list, <accept_record_list>
However, there's a typo here and the record is added into the same original list (<accept_field_list>),
not into the <accept_record_list>.

This results in looping over and over the same list with 100% CPU load, and also memory issues
(because arbitrary not necessary 0-terminated pieces of memory are being strdup'ed).
