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 netstat(1) utility displays the contents of various network related data
|
|
structures.
|
|
|
|
II. Problem Description
|
|
|
|
The netstat(1) utility incorrectly handles reported values on 32-bit systems.
|
|
|
|
III. Impact
|
|
|
|
Due to how netstat(1) processes IPSEC counters, the utility may produce
|
|
incorrect output on 32-bit systems.
|
|
|
|
IV. Workaround
|
|
|
|
No workaround is available, however systems without IPSEC compiled into the
|
|
kernel 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-15:12/netstat.patch
|
|
# fetch https://security.FreeBSD.org/patches/EN-15:12/netstat.patch.asc
|
|
# gpg --verify netstat.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>.
|
|
|
