Background - -SCTP protocol provides reliable, flow-controlled, two-way transmission -of data. It is a message oriented protocol and can support the SOCK_STREAM -and SOCK_SEQPACKET abstractions. - -II. Problem Description - -The input validation of received SCTP RE_CONFIG chunks is insufficient, -and can result in a NULL pointer deference later. - -III. Impact - -A remote attacker who can send a malformed SCTP packet to a FreeBSD system -that serves SCTP can cause a kernel panic, resulting in a Denial of -Service. - -IV. Workaround - -On FreeBSD 10.1 or later systems, the system administrator can set -net.inet.sctp.reconfig_enable to 0 to disable processing of RE_CONFIG -chunks. This workaround is not available on earlier FreeBSD releases, -but systems that do not serve SCTP connections are not vulnerable. - -V. Solution - -Perform one of the following: - -1) Upgrade your vulnerable system to a supported FreeBSD stable or -release / security branch (releng) dated after the correction date. - -2) 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 - -3) 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-15:03/sctp.patch -# fetch https://security.FreeBSD.org/patches/SA-15:03/sctp.patch.asc -# gpg --verify sctp.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.
