Package        : ecryptfs-utils
CVE ID         : CVE-2016-1572

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.
