** Description changed: - The dropbear package includes an initramfs script, /usr/share/initramfs- - tools/scripts/init-premount/devpts, that mounts devpts a second time, - after it's already been mounted by /usr/share/initramfs-tools/init, - provided by initramfs-tools. + [Impact] + The dropbear package includes an initramfs script, /usr/share/initramfs-tools/scripts/init-premount/devpts, that mounts devpts a second time, after it's already been mounted by /usr/share/initramfs-tools/init, provided by initramfs-tools. + [Test Case] Line 23 in /usr/share/initramfs-tools/scripts/init-premount/devpts from dropbear: mount -t devpts none /dev/pts Line 25 in /usr/share/initramfs-tools/init from initramfs-tools: mount -t devpts -o noexec,nosuid,gid=5,mode=0620 devpts /dev/pts || true + The second mount from dropbear fails since /dev/pts is already mounted, + but it does change the mount options: - The second mount from dropbear fails since /dev/pts is already mounted, but it does change the mount options: - - mwharris@mwharris-test:~$ grep pts /proc/mounts + mwharris@mwharris-test:~$ grep pts /proc/mounts devpts /dev/pts devpts rw,nosuid,noexec,relatime,mode=600,ptmxmode=000 0 0 I'm not sure why dropbear tried to mount devpts a second time, but it seems like the best fix would just be to remove /usr/share/initramfs- tools/scripts/init-premount/devpts from dropbear I'm on Precise using dropbear_2011.54-1 and initramfs-tools_0.99ubuntu10 + + [Regression Potential] + Minimal, as this would only remove mounting /dev/pts a second time and is not introducing any extra functionality.
