Package: kexec-tools Version: 1:2.0.7-3 Severity: normal The new coldreboot mechanism uses a flag file with a hardcoded name in a world-writable directory, which is generally considered a bad idea. Unprivileged users can trivially sabotage attempts to do a "warm" kexec-reload - indeed, they can even do so *accidentally*!
All that needs to happen is that somebody notices the existence of coldreboot and idly tries "/sbin/coldreboot --help" - which creates the flag file before invoking "reboot --help". Then months later when the admin needs to do a quick warm reboot into a new kernel the machine mysteriously fails to cooperate, and the clues to what went wrong are erased in the process. -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (990, 'testing'), (50, 'unstable') Architecture: i386 (i686) Kernel: Linux 3.17-1-686-pae (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages kexec-tools depends on: ii debconf [debconf-2.0] 1.5.53 ii libc6 2.19-11 kexec-tools recommends no packages. kexec-tools suggests no packages. -- debconf information: kexec-tools/use_grub_config: false * kexec-tools/load_kexec: true -- JBR with qualifications in linguistics, experience as a Debian sysadmin, and probably no clue about this particular package -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
