Package        : shadow
CVE ID         : CVE-2016-6252 CVE-2017-2616
Debian Bug     : 832170 855943

Several vulnerabilities were discovered in the shadow suite. The Common
Vulnerabilities and Exposures project identifies the following problems:

CVE-2016-6252

    An integer overflow vulnerability was discovered, potentially
    allowing a local user to escalate privileges via crafted input to
    the newuidmap utility.

CVE-2017-2616

    Tobias Stoeckmann discovered that su does not properly handle
    clearing a child PID. A local attacker can take advantage of this
    flaw to send SIGKILL to other processes with root privileges,
    resulting in denial of service.

For the stable distribution (jessie), these problems have been fixed in
version 1:4.2-3+deb8u3.

We recommend that you upgrade your shadow packages.
