Hello,
$ lspci -i x
Segmentation fault
(file x must not exist to reproduce this)
Problem is in lib/names-parse.c:33
static pci_file pci_open(struct pci_access *a)
{
pci_file result;
size_t len;
char *new_name;
result = gzopen(a->id_file_name, "rb");
if (result)
return result;
len = strlen(a->id_file_name);
if (len >= 3 && memcmp(a->id_file_name + len - 3, ".gz", 3) != 0)
return result;
/* Here's the bug. It is assumed that the file name ends in .gz even if
it's shorter than 3 chars */
new_name = malloc(len - 2);
memcpy(new_name, a->id_file_name, len - 3);
new_name[len - 3] = 0;
pci_set_name_list_path(a, new_name, 1);
return gzopen(a->id_file_name, "rb");
}
Patch:
if (len < 3 || memcmp(a->id_file_name + len - 3, ".gz", 3) != 0)
return result;
Cheers,
Joern Heissler
