+
+Topic: Regression in pw(8) when creating numeric users or groups
+
+Category: core
+Module: pw
+Announced: 2015-09-16
+Credits: Thierry Caillet, Baptiste Daroussin
+Affects: 10.2-RELEASE
+Corrected: 2015-08-23 21:42:27 UTC (stable/10, 10.2-STABLE)
+ 2015-09-16 20:59:41 UTC (releng/10.2, 10.2-RELEASE-p3)
+
+For general information regarding FreeBSD Errata Notices and Security
+Advisories, including descriptions of the fields above, security
+branches, and the following sections, please visit
+<URL:https://security.freebsd.org/>.
+
+I. Background
+
+The pw(8) utility is used to create, remove, modify, and display system
+users and groups.
+
+II. Problem Description
+
+The pw(8) utility will fail to create users and groups that only contain
+numeric values [0-9].
+
+III. Impact
+
+An attempt to create a user or group containing only numeric values will
+fail.
+
+IV. Workaround
+
+No workaround is available, but systems configured to create users or groups
+that do not contain numeric-only names are not affected.
+
+V. Solution
+
+Perform one of the following:
+
+1) Upgrade your system to a supported FreeBSD stable or release / security
+branch (releng) dated after the correction date.
+
+2) To update your present system via a binary patch:
+
+Systems running a RELEASE version of FreeBSD on the i386 or amd64
+platforms can be updated via the freebsd-update(8) utility:
+
+# freebsd-update fetch
+# freebsd-update install
+
+3) To update your present system via a source code patch:
+
+The following patches have been verified to apply to the applicable
+FreeBSD release branches.
+
+a) Download the relevant patch from the location below, and verify the
+detached PGP signature using your PGP utility.
+
+# fetch https://security.FreeBSD.org/patches/EN-15:26/pw.patch
+# fetch https://security.FreeBSD.org/patches/EN-15:26/pw.patch.asc
+# gpg --verify pw.patch.asc
+
+b) Apply the patch. Execute the following commands as root:
+
+# cd /usr/src
+# patch < /path/to/patch
+
+c) Recompile the operating system using buildworld and installworld as
+described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.
+
+A reboot of the running system is not necessary after installing the updated
+pw(8) utility.
+
+VI. Correction details
+
+The following list contains the correction revision numbers for each
+affected branch.

+FreeBSD-EN-15:17.libc Errata Notice
+ The FreeBSD Project
+
+Topic: libc incorrectly handles signals for multi-threaded processes
+
+Category: core
+Module: libc
+Announced: 2015-09-16
+Credits: Konstantin Belousov
+Affects: FreeBSD 10.2
+Corrected: 2015-09-05 08:55:51 UTC (stable/10, 10.2-STABLE)
+ 2015-09-16 20:59:41 UTC (releng/10.2, 10.2-RELEASE-p3)
+
+For general information regarding FreeBSD Errata Notices and Security
+Advisories, including descriptions of the fields above, security
+branches, and the following sections, please visit
+<URL:https://security.freebsd.org/>.
+
+I. Background
+
+The FreeBSD libc library is the core C runtime library which implements
+the ANSI C, POSIX APIs and BSD extensions for applications on top of the
+FreeBSD kernel. The internal operations of libc change when the threading
+library is loaded, ensuring service implementations are operational in
+multi-threaded environments, while avoiding unnecessary overhead for
+applications not utilizing threads. The implementation of some services
+is delegated to the threading library, for instance, the signal management.
+
+II. Problem Description
+
+Signal-related services, such as signal(3), sigprocmask(2), and sigwait(2)
+are not properly redirected to the threading library implementation when
+used by libc directly.
+
+III. Impact
+
+The full impact of the bug is difficult to enumerate precisely based on the
+nature of the problem, though some visible effects include runtime linker
+hang during signal delivery, and delivery of a signal to the application
+at an unexpected time.
+
+IV. Workaround
+
+No workaround is available.
+
+V. Solution
+
+Perform one of the following:
+
+1) Upgrade your system to a supported FreeBSD stable or release / security
+branch (releng) dated after the correction date.
+
+2) To update your present system via a binary patch:
+
+Systems running a RELEASE version of FreeBSD on the i386 or amd64

+b) Apply the patch. Execute the following commands as root:

+
+c) Recompile the operating system using buildworld and installworld as

+FreeBSD-EN-15:18.pkg Errata Notice

+Topic: Implement pubkey support for pkg(7) bootstrap
+
+Category: core
+Module: pkg
+Announced: 2015-09-16
+Credits: Baptiste Daroussin
+Affects: All supported versions of FreeBSD.
+Corrected: 2015-09-15 05:56:16 UTC (stable/10, 10.2-STABLE)
+ 2015-09-16 20:59:41 UTC (releng/10.2, 10.2-RELEASE-p3)

+For general information regarding FreeBSD Errata Notices and Security
+Advisories, including descriptions of the fields above, security
+branches, and the following sections, please visit
+<URL:https://security.freebsd.org/>.
+
+I. Background
+
+The pkg(8) utility is the package management tool for FreeBSD. The base
+system includes a pkg(7) bootstrap utility used to install the latest
+pkg(8) utility.
+
+II. Problem Description
+
+The pubkey method is not supported by the pkg(7) bootstrap utility.
+Previously, before EN-15:15.pkg, if the system administrator requested
+this method, it is silently ignored and no check is performed.
+
+In EN-15:15.pkg, pkg(7) have been modified to issue warning and refuse
+to proceed any further.
+
+III. Impact
+
+There is no way to use the pubkey method to bootstrap pkg(8) on the
+system.
+
+IV. Workaround
+
+No workaround is available, but the default FreeBSD configuration is not
+affected because it uses "fingerprint" method.
+
+V. Solution
+
+Perform one of the following:
+
+1) Upgrade your system to a supported FreeBSD stable or release / security
+branch (releng) dated after the correction date.
+
+2) To update your present system via a binary patch:
+
+Systems running a RELEASE version of FreeBSD on the i386 or amd64
