Background + +The dbopen(3) with DB_HASH allows reading and writing to database files +in the hash(3) format. Examples of such files are the system master +passwd and services databases in /etc. In FreeBSD 10.3 operations +using dbopen(3) were fixed to always call fsync(2) on their files when +writing to ensure they were consistent after a power loss. This was +mostly noticeable for the user and group database files after using +pw, vipw, chpass, etc. + +II. Problem Description + +The changes in FreeBSD 10.3 to use fsync(2) were improperly extended to +operations that were read-only. + +III. Impact + +This could manifest as extreme slowdowns in operations that read from one +of these files, such as the user database. It was especially noticeable +during the use of "pkg install" since it reads from the user database. It +could also incur excessive I/O writes to these files if the file system +was not mounted with noatime which could lessen the lifetime of SSD. + +IV. Workaround + +No workaround is available. + +V.

Background + +Each CPU in an x86 system contains an interrupt controller (local APIC) +used to handle both external interrupts and inter-processor-interrupts +(IPIs). + +II. Problem Description + +In xAPIC mode, the local APIC can only queue a single IPI at a time. If +a previously queued IPI is still pending when a CPU attempts to send an +IPI, it spins waiting for the previous IPI to complete. A change merged +prior to 10.2-RELEASE altered this loop to check the state of the previous +IPI once every 5 microseconds rather than constantly polling. + +III. Impact + +Checking the status of the previous IPI once every 5 microseconds could +introduce 5 microsecond delays when sending IPIs.

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.

Background + +FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is +a collaborative effort to develop a robust, commercial-grade, full-featured +Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) +and Transport Layer Security (TLS v1) protocols as well as a full-strength +general purpose cryptography library. + +II. Problem Description + +The padding check in AES-NI CBC MAC was rewritten to be in constant time +by making sure that always the same bytes are read and compared against +either the MAC or padding bytes. But it no longer checked that there was +enough data to have both the MAC and padding bytes. [CVE-2016-2107] + +An overflow can occur in the EVP_EncodeUpdate() function which is used for +Base64 encoding of binary data. [CVE-2016-2105] + +An overflow can occur in the EVP_EncryptUpdate() function, however it is +believed that there can be no overflows in internal code due to this problem. +[CVE-2016-2106] + +When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio() +a short invalid encoding can casuse allocation of large amounts of memory +potentially consuming excessive resources or exhausting memory. +[CVE-2016-2109] + +ASN1 Strings that are over 1024 bytes can cause an overread in applications +using the X509_NAME_oneline() function on EBCDIC systems. [CVE-2016-2176] +FreeBSD does not run on any EBCDIC systems and therefore is not affected. + +III. Impact + +A MITM attacker can use a padding oracle attack to decrypt traffic +when the connection uses an AES CBC cipher and the server support +AES-NI. [CVE-2016-2107] + +If an attacker is able to supply very large amounts of input data then a +length check can overflow resulting in a heap corruption. [CVE-2016-2105] + +Any application parsing untrusted data through d2i BIO functions are vulnerable +to memory exhaustion attack. [CVE-2016-2109] TLS applications are not affected. + +IV. Workaround + +No workaround is available. + +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. + +Restart all daemons that use the library, or reboot the system. + +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 + +Restart all daemons that use the library, or reboot the system. + +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. + +[FreeBSD 10.x] +# fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-10.patch +# fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-10.patch.asc +# gpg --verify openssl-10.patch.asc + +[FreeBSD 9.3] +# fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-9.patc +# fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-9.patch.asc +# gpg --verify openssl-9.patch.asc + +b) Apply the patch.
