Here is the fix of the problem: Use the right type for `len`, avoid segmentation fault
`getline()` requires its second parameter to be `size_t *`. On the amd64 platform the size of `unsigned int` is 4 and the size of `size_t` is 8 bytes. Using a wrong pointer type can lead to a stack variables corruption (overwriting with zeros) and a segmentation fault later. See also similar `len` declarations in `_discover_get_pci_raw_sys()` in the docs and `_discover_get_ata_raw()` / `discover_get_pci_raw_proc()` / `discover_get_usb_raw()` in the source code. ** Patch added: "0001-Use-the-right-type-for-len-avoid-segmentation-fault.diff" https://bugs.launchpad.net/discover/+bug/1718687/+attachment/4954403/+files/0001-Use-the-right-type-for-len-avoid-segmentation-fault.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1718687 Title: crash on amd64 To manage notifications about this bug go to: https://bugs.launchpad.net/discover/+bug/1718687/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
