Background - -ZFS is one of several filesystems available on FreeBSD. ZFS supports many -advanced features, including snapshots, which provides a frozen read-only -image of file system at a given time. - -File system snapshots can be accessed under the .zfs/snapshot directory -in the root of the file system. - -II. Problem Description - -There is a memory leak in the error path when mounting a snapshot via the -automatic .zfs/snapshot directory, which can be triggered when the snapshot -was once mounted, but later deleted by the system administrator. - -III. Impact - -A local user may be able to trigger the memory leak multiple times and -eventually exhaust kernel memory, if the user knows a snapshot and access -it before the system administrator deletes it. - -IV. Workaround - -No workaround is available, but systems that do not use ZFS snapshots 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. - -Reboot is required. - -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 - -Reboot is required. - -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. - -# fetch https://security.FreeBSD.org/patches/EN-16:08/zfs.patch -# fetch https://security.FreeBSD.org/patches/EN-16:08/zfs.patch.asc -# gpg --verify zfs.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.
