+FreeBSD-EN-18:08.lazyfpu Errata Notice
+ The FreeBSD Project
+
+Topic: LazyFPU remediation causes potential data corruption
+
+Category: core
+Module: kernel
+Announced: 2018-09-12
+Credits: Gleb Kurtsou
+Affects: FreeBSD 10.4-STABLE, 11.1 and later.
+Corrected: 2018-07-31 10:18:30 UTC (stable/11, 11.1-STABLE)
+ 2018-09-12 05:08:49 UTC (releng/11.2, 11.2-RELEASE-p3)
+ 2018-09-12 05:08:49 UTC (releng/11.1, 11.1-RELEASE-p14)
+ 2018-08-03 14:12:37 UTC (stable/10, 10.4-STABLE)
+
+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/>.
+
+Special Note: While SA-18:07.lazyfpu has been fixed in 10.4-STABLE, it has
+yet to be released for 10.4-RELEASE. As such, this EN does not apply for
+that release. Once SA-18:07.lazyfpu has been updated for 10.4-RELEASE,
+this EN will be incorporated at that time.
+
+I. Background
+
+The recent security advisory titled SA-18:07.lazyfpu resolved an issue in the
+floating point unit (FPU) state handling.
+
+II. Problem Description
+
+As a result of fixing the issue described in SA-18:07.lazyfpu, a regression
+was introduced. FPU state manipulation did not sufficiently prevent context
+switches potentially allowing partially modified FPU context to be switched
+out. Upon returning the thread to a running state, stale FPU context could
+be reloaded.
+
+III. Impact
+
+The regression could potentially cause an inconsistent FPU state, leading to
+data corruption.
+
+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.
+
+Afterward, reboot the system.
+
+2) To update your 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
+
+Afterward, reboot the system.
+
+3) To update your 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.
+
+[FreeBSD 11.x]
+# fetch https://security.FreeBSD.org/patches/EN-18:08/lazyfpu-11.patch
+# fetch https://security.FreeBSD.org/patches/EN-18:08/lazyfpu-11.patch.asc
+# gpg --verify lazyfpu-11.patch.asc
+
+b) Apply the patch. Execute the following commands as root:
+
+# cd /usr/src
+# patch < /path/to/patch
+
+c) Recompile your kernel as described in
+<URL:https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the
+system.
+
+VI. Correction details
+
+The following list contains the correction revision numbers for each
+affected branch.

+Topic: Improper ELF header parsing
+
+Category: core
+Module: kernel
+Announced: 2018-09-12
+Credits: Thomas Barabosch, Fraunhofer FKIE; Mark Johnston
+Affects: All supported versions of FreeBSD.
+Corrected: 2018-09-12 05:02:11 UTC (stable/11, 11.1-STABLE)
+ 2018-09-12 05:07:35 UTC (releng/11.2, 11.2-RELEASE-p3)
+ 2018-09-12 05:07:35 UTC (releng/11.1, 11.1-RELEASE-p14)

+ 2018-09-12 05:07:35 UTC (releng/10.4, 10.4-RELEASE-p12)
+CVE Name: CVE-2018-6924
+
+For general information regarding FreeBSD Security Advisories,
+including descriptions of the fields above, security branches, and the
+following sections, please visit <URL:https://security.FreeBSD.org/>.
+
+I. Background
+
+To execute a binary the kernel must parse the ELF header to determine the
+entry point address, the program interpreter, and other parameters.
+
+II. Problem Description
+
+Insufficient validation was performed in the ELF header parser, and malformed
+or otherwise invalid ELF binaries were not rejected as they should be.
+
+III. Impact
+
+Execution of a malicious ELF binary may result in a kernel crash or may
+disclose kernel memory.
+
+IV. Workaround
+
+No workaround is available.
+
+V. Solution
+
+Upgrade your vulnerable system to a supported FreeBSD stable or
+release / security branch (releng) dated after the correction date, and
+reboot.
+
+1) To update your vulnerable 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
+# shutdown -r +30 "Rebooting for security update"
+
+2) To update your vulnerable 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/SA-18:12/elf.patch
+# fetch https://security.FreeBSD.org/patches/SA-18:12/elf.patch.asc
+# gpg --verify elf.patch.asc
+
+b) Apply the patch. Execute the following commands as root:
+
+# cd /usr/src
+# patch < /path/to/patch
+
+c) Recompile your kernel as described in
+<URL:https://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the
+system.
