UCS 4.0 is not affected by these: * CVE-2015-7848 CVE-2015-7849 CVE-2015-7854 (Vulnerable code introduced in 4.2.7) * CVE-2015-7853 (Vulnerable code introduced in 4.2.8) Applicability CVE-2015-7705 is still a bit unclear to me, see https://lists.debian.org/debian-lts/2015/10/msg00028.html, the tracker currently says "Default config not affected". So let's postpone that. So upstream Debian package version 1:4.2.6.p5+dfsg-2+deb7u6 fixes these issues: CVE ID : CVE-2014-9750 CVE-2014-9751 CVE-2015-3405 CVE-2015-5146 CVE-2015-5194 CVE-2015-5195 CVE-2015-5219 CVE-2015-5300 CVE-2015-7691 CVE-2015-7692 CVE-2015-7701 CVE-2015-7702 CVE-2015-7703 CVE-2015-7704 CVE-2015-7850 CVE-2015-7852 CVE-2015-7855 CVE-2015-7871 Descriptions for the additional minor issues fixed in the DSA: * when Autokey Authentication is enabled, ntp_crypto.c allows remote attackers to obtain sensitive information from process memory or cause a denial of service (daemon crash) via a crafted packet (CVE-2014-9750) * The read_network_packet function in ntp_io.c does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by leveraging the ability to reach the ntpd machine's network interface with a packet from the ::1 address (CVE-2014-9751) * ntp-keygen may generate non-random symmetric keys on big-endian systems (CVE-2015-3405) * ntpd control message crash: Crafted NUL-byte in configuration directive (CVE-2015-5146) * crash with crafted logconfig configuration command (CVE-2015-5194) * ntpd crash when processing config commands with statistics type (CVE-2015-5195) * infinite loop in sntp processing crafted packet (CVE-2015-5219) Tests (i386): OK Advisory: ntp.yaml r65913 OK: DEBIAN_FRONTEND=noninteractive apt-get install --reinstall -y ntp OK: Tests: # ntptrace 192.168.0.3 # ntptime # ntpdate -u 127.0.0.1 |
