Package : chrony
Version : 1.24-3.1+deb7u4
CVE ID : CVE-2016-1567
Debian Bug : 812923 568492
It was discovered that Chrony, a versatile implementation of the
Network Time Protocol, did not verify peer associations of symmetric
keys when authenticating packets, which might allow remote attackers
to conduct impersonation attacks via an arbitrary trusted key, aka a
"skeleton key."
This update also resolves Debian bug #568492.
For Debian 7 "Wheezy", these problems have been fixed in version
1.24-3.1+deb7u4.
We recommend that you upgrade your chrony packages.
