Within tcpreplay's tcprewrite, a double free vulnerability has been identified
in the dlt_linuxsll2_cleanup() function in plugins/dlt_linuxsll2/linuxsll2.c.
This vulnerability is triggered when tcpedit_dlt_cleanup() indirectly invokes
the cleanup routine multiple times on the same memory region. By supplying a
specifically crafted pcap file to the tcprewrite binary, a local attacker can
exploit this flaw to cause a Denial of Service (DoS) via memory corruption.
