-------------------------------------
Summary: Memory corruption in
axis2_http_transport_utils_process_accept_headers()
Key: AXIS2C-1597
URL: https://issues.apache.org/jira/browse/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
axis2_http_transport_utils_process_accept_headers().
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).
