    Jann Horn discovered that the setuid-root mount.ecryptfs_private helper
    in the ecryptfs-utils would mount over any target directory that the
    user owns, including a directory in procfs. A local attacker could use
    this flaw to escalate his privileges.
    
    For the oldstable distribution (wheezy), this problem has been fixed
    in version 99-1+deb7u1.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 103-5+deb8u1.
    
    We recommend that you upgrade your ecryptfs-utils packages.
