Debian Security Advisory DSA-3793-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 24, 2017 https://www.debian.org/security/faq
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.
