Detail
| A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog) The following packages are affected: mount The problem can be corrected by upgrading the affected package to version 2.12-7ubuntu6.1 (for Ubuntu 4.10), or 2.12p-2ubuntu2.2 (for Ubuntu 5.04). In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: David Watson discovered that "umount -r" removed some restrictive mount options like the "nosuid" flag. If /etc/fstab contains user-mountable removable devices which specify the "nosuid" flag (which is common practice for such devices), a local attacker could exploit this to execute arbitrary programs with root privileges by calling "umount -r" on a removable device. This does not affect the default Ubuntu configuration. Since Ubuntu mounts removable devices automatically, there is normally no need to configure them manually in /etc/fstab. |

| Title: | umount in util-linux 2.8 to 2.12q, 2.13-pre1, and 2.13-pre2, and other packages such as loop-aes-utils, allows local users with unmount permissions to gain privileges via the -r (remount) option, which causes the file system to be remounted with just the read-only flag, which effectively clears the nosuid, nodev, and other flags. | ||
