Description Andrej Nemec 2016-07-07 11:38:11 UTC

tcprewrite program, part of the tcpreplay suite, does not check the size of the frames it processes. Huge frames may trigger a segmentation fault, as they occur on interfaces with an MTU of or close to 65536. For example, the loopback interface lo of the Linux kernel has such a value.
