>Description:
Under some circumstances, loading history in libedit by history(H_LOAD) causes abnormal program termination due to invalid memory access on line 693 of /usr/src/lib/libedit/history.c.
>How-To-Repeat:
>Fix:
Compile the following program with ElectricFence
#include <histedit.h>
int main(int argc, char* argv[])
{
History* h = history_init();
HistEvent ev;
history(h, &ev, H_LOAD, argv[1]);
return 0;
}
and run it with a history file 4096 bytes long containing
_HiStOrY_V2_
def0123456789abcdef0123456789abcdef0123456789abcde
followed by 63 copies of line:
0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcde
