I. Background libfetch(3) is a multi-protocol file transfer library included with FreeBSD and used by the fetch(1) command-line tool, pkg(8) package manager, and others. II. Problem Description A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers. III. Impact An attacker in control of the URL to be fetched (possibly via HTTP redirect) may cause a heap buffer overflow, resulting in program misbehavior or malicious code execution. 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. Perform one of the following: 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 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-20:01/libfetch.patch # fetch https://security.FreeBSD.org/patches/SA-20:01/libfetch.patch.asc # gpg --verify libfetch.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 . Restart all daemons that use the library, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch.

I. Background IPsec is a suite of protocols providing data authentication, integrity, and confidentiality between two networked hosts. II. Problem Description A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint. III. Impact The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause an action that was intentionally performed once to be repeated. IV. Workaround No workaround is available. Systems not using IPsec are not vulnerable. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date, and reboot.
