- CVEs with nessus.description==eCryptfs is a stacked, cryptographic file system. It is transparent to the underlying file system and provides per-file granularity.
The setuid mount.ecryptfs_private utility allows users to mount an eCryptfs file system. This utility can only be run by users in the 'ecryptfs' group.
A race condition flaw was found in the way mount.ecryptfs_private checked the permissions of a requested mount point when mounting an encrypted file system. A local attacker could possibly use this flaw to escalate their privileges by mounting over an arbitrary directory.
(CVE-2011-1831)
A race condition flaw in umount.ecryptfs_private could allow a local attacker to unmount an arbitrary file system. (CVE-2011-1832)
It was found that mount.ecryptfs_private did not handle certain errors correctly when updating the mtab (mounted file systems table) file, allowing a local attacker to corrupt the mtab file and possibly unmount an arbitrary file system. (CVE-2011-1834)
An insecure temporary file use flaw was found in the ecryptfs-setup-private script. A local attacker could use this script to insert their own key that will subsequently be used by a new user, possibly giving the attacker access to the user's encrypted data if existing file permissions allow access. (CVE-2011-1835)
A race condition flaw in mount.ecryptfs_private could allow a local attacker to overwrite arbitrary files. (CVE-2011-1837)
A race condition flaw in the way temporary files were accessed in mount.ecryptfs_private could allow a malicious, local user to make arbitrary modifications to the mtab file. (CVE-2011-3145)
A race condition flaw was found in the way mount.ecryptfs_private checked the permissions of the directory to mount. A local attacker could use this flaw to mount (and then access) a directory they would otherwise not have access to. Note: The fix for this issue is incomplete until a kernel-space change is made. Future Scientific Linux 5 and 6 kernel updates will correct this issue. (CVE-2011-1833)
Users of ecryptfs-utils are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
