After updating via the binary patch method with freebsd-update, uname still reports 9.2-RELEASE-p7 even after reboot. An additional freebsd-update after this initial update however does not report anything new to update (aside from the ongoing persistent /boot/kernel/linker.hints). Same result on 3 amd64 systems so far. -scott On 06/05/14 09:16, FreeBSD Security Advisories wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA512 > > ============================================================================= > FreeBSD-SA-14:14.openssl Security Advisory > The FreeBSD Project > > Topic: OpenSSL multiple vulnerabilities > > Category: contrib > Module: openssl > Announced: 2014-06-05 > Affects: All supported versions of FreeBSD. > Corrected: 2014-06-05 12:32:38 UTC (stable/10, 10.0-STABLE) > 2014-06-05 12:33:23 UTC (releng/10.0, 10.0-RELEASE-p5) > 2014-06-05 12:53:06 UTC (stable/9, 9.3-BETA1) > 2014-06-05 12:53:06 UTC (stable/9, 9.3-BETA1-p2) > 2014-06-05 12:33:23 UTC (releng/9.2, 9.2-RELEASE-p8) > 2014-06-05 12:33:23 UTC (releng/9.1, 9.1-RELEASE-p15) > 2014-06-05 12:32:38 UTC (stable/8, 8.4-STABLE) > 2014-06-05 12:33:23 UTC (releng/8.4, 8.4-RELEASE-p12) > CVE Name: CVE-2014-0195, CVE-2014-0221, CVE-2014-0224, CVE-2014-3470 > > For general information regarding FreeBSD Security Advisories, > including descriptions of the fields above, security branches, and the > following sections, please visit <URL:http://security.FreeBSD.org/>. > > I.
