    Package : ntp
    CVE ID : CVE-2014-9293 CVE-2014-9294 CVE-2014-9295 CVE-2014-9296
    Debian Bug : 773576

    Several vulnerabilities were discovered in the ntp package, an
    implementation of the Network Time Protocol.

    CVE-2014-9293

    ntpd generated a weak key for its internal use, with full
    administrative privileges. Attackers could use this key to
    reconfigure ntpd (or to exploit other vulnerabilities).

    CVE-2014-9294

    The ntp-keygen utility generated weak MD5 keys with insufficient
    entropy.

    CVE-2014-9295

    ntpd had several buffer overflows (both on the stack and in the
    data section), allowing remote authenticated attackers to crash
    ntpd or potentially execute arbitrary code.

    CVE-2014-9296

    The general packet processing function in ntpd did not handle an
    error case correctly.

    The default ntpd configuration in Debian restricts access to localhost
    (and possible the adjacent network in case of IPv6).

    Keys explicitly generated by "ntp-keygen -M" should be regenerated.

    For the stable distribution (wheezy), these problems have been fixed in
    version 1:4.2.6.p5+dfsg-2+deb7u1.

    We recommend that you upgrade your ntp packages.
