--- Begin Message ---Package: libefivar0 Version: 0.12-1 Severity: critical Justification: breaks the whole system Upgrading libefivar0 from version 0.10-5 to 0.12-1 causes a segmentation fault when running efibootmgr without arguments (I tried it with both efibootmgr 0.7.0-2 and 0.9.0-1). I'm not quite sure if severity critical is justified, but I think a broken efibootmgr is at least potentially able to break the whole system. gdb pointed to libefivar.so.0 which has no debugging symbols, so I built my own and that one crashes in vars.c line 165 with var == NULL. The last two lines in an strace log before the crash are open("/sys/firmware/efi/vars/Boot0005-8be4[...]/raw_var", O_RDONLY) = 3 read(3, [...], 4096) = -1 EIO (Input/output error) (Sorry, no copy&paste, just read&type; the system in question has only very limited network connectivity at the moment and I'm sending this report from a different system.) var is apparently returned from a call to read_file() a few lines above. The source code history shows that read_fd() has recently been replaced by read_file(), but they behave differently after read errors. In particular, read_file() resets the buffer to NULL whereas read_fd() didn't.
