Thread: overlapping memcpy

  1. overlapping memcpy

    Hi,
    Valgrind has found a problem related to an overlapping memcpy in mod_ssl
    (Apache/2.2.9 (Unix)), here is the output:

    ==18546== Thread 5:
    ==18546== Source and destination overlap in memcpy(0x425E0E8, 0x425E10E,
    141)
    ==18546== at 0x4007A42: memcpy (mc_replace_strmem.c:402)
    ==18546== by 0x446C464: ssl_io_input_read (in
    /usr/local/apache2/modules/mod_ssl.so)
    ==18546== by 0x446C781: ssl_io_filter_input (in
    /usr/local/apache2/modules/mod_ssl.so)
    ==18546== by 0x8068DB5: ap_rgetline_core (in
    /usr/local/apache2/bin/httpd)
    ==18546== by 0x80690CE: ap_get_mime_headers_core (in
    /usr/local/apache2/bin/httpd)
    ==18546== by 0x80696FC: ap_read_request (in /usr/local/apache2/bin/httpd)
    ==18546== by 0x80799DA: ap_process_http_connection (in
    /usr/local/apache2/bin/httpd)
    ==18546== by 0x8076CEC: ap_run_process_connection (in
    /usr/local/apache2/bin/httpd)
    ==18546== by 0x807FFD3: worker_thread (in /usr/local/apache2/bin/httpd)
    ==18546== by 0x4057603: dummy_worker (in
    /usr/local/apache2/lib/libapr-1.so.0.3.0)
    ==18546== by 0x8E145A: start_thread (in /lib/libpthread-2.5.so)
    ==18546== by 0x71323D: clone (in /lib/libc-2.5.so)

    This happens when an axis2 client sends a https request.
    Let me know if you need more information.
