Package : shadow
Version : 4.1.5.1-1+deb7u1
CVE ID : CVE-2017-2616
Debian Bug : 855943
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 Debian 7 "Wheezy", these problems have been fixed in version
4.1.5.1-1+deb7u1.
We recommend that you upgrade your shadow packages.
