util-linux vulnerability Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - bsdutils - mount - util-linux - util-linux-locales Description : 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 rights 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. Solution : Upgrade to : - bsdutils-2.12p-2ubuntu2.2 (Ubuntu 5.04) - mount-2.12p-2ubuntu2.2 (Ubuntu 5.04) - util-linux-2.12p-2ubuntu2.2 (Ubuntu 5.04) - util-linux-locales-2.12p-2ubuntu2.2 (Ubuntu 5.04) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
