possible fix for buffer overrun #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Line 49 of procnamemodule.c line 49 is:

strncpy(argv[0], name , strlen(name));

For a really long name this risks overwriting other arguments. It seems
safer to do:

strncpy(argv[0], name , strlen(argv[0]));

I think the name should have 16 bytes max, respecting the PR_SET_NAME option in 
the
prctl() call:
