Description Hanno Böck gentoo-dev 2015-10-22 10:33:14 UTC
The summary line is too short to hold all CVEs, they are:
CVE-2015-7691, CVE-2015-7692, CVE-2015-7701, CVE-2015-7702, CVE-2015-7703, CVE-2015-7704, CVE-2015-7705, CVE-2015-7848, CVE-2015-7849, CVE-2015-7850, CVE-2015-7851, CVE-2015-7852, CVE-2015-7853, CVE-2015-7854, CVE-2015-7855, CVE-2015-7871

Upstream advisory:

The latest ntp release 4.2.8_p4 fixes various security vulnerabilities. Some of them are related to a research paper from Boston University (worth reading) about NTP security:

Seems no single one of the bugs is super-serious, the most serious one is a crypto bypass for symmetric authentication (which is rarely used as far as I'm aware).

Please bump.

I have bumped net-misc/ntp to 4.2.8_p4 after asking WilliamH for permission to touch a base-system package.

Maintainer(s), please advise if you when you are ready for stabilization or call for stabilization yourself.
Comment 3 SpanKY gentoo-dev 2015-11-03 21:07:20 UTC
the code is generally fine, but the tests have gotten ... bad
