Package        : ntp
CVE ID         : CVE-2014-9297 CVE-2014-9298

Several vulnerabilities were discovered in the ntp package, an
implementation of the Network Time Protocol. The Common Vulnerabilities
and Exposures project identifies the following problems:

CVE-2014-9297

    Stephen Roettger of the Google Security Team, Sebastian Krahmer of
    the SUSE Security Team and Harlan Stenn of Network Time Foundation
    discovered that the length value in extension fields is not properly
    validated in several code paths in ntp_crypto.c, which could lead to
    information leakage or denial of service (ntpd crash).

CVE-2014-9298

    Stephen Roettger of the Google Security Team reported that ACLs
    based on IPv6 ::1 addresses can be bypassed.

For the stable distribution (wheezy), these problems have been fixed in
version 1:4.2.6.p5+dfsg-2+deb7u2.

For the unstable distribution (sid), these problems have been fixed in
version 1:4.2.6.p5+dfsg-4.

We recommend that you upgrade your ntp packages.
