I. Background The file(1) utility attempts to classify file system objects based on filesystem, magic number and language tests. The libmagic(3) library provides most of the functionality of file(1) and may be used by other applications. II. Problem Description There are a number of denial of service issues in the ELF parser used by file(1). III. Impact An attacker who can cause file(1) or any other applications using the libmagic(3) library to be run on a maliciously constructed input can cause the application to crash or consume excessive CPU resources, resulting in a denial-of-service. IV. Workaround No workaround is available, but systems where file(1) and other libmagic(3)-using applications are never run on untrusted input 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.

I. Background BIND 9 is an implementation of the Domain Name System (DNS) protocols. The named(8) daemon is an Internet Domain Name Server. II. Problem Description By causing queries to be made against a maliciously-constructed zone or against a malicious DNS server, an attacker who is able to cause specific queries to be sent to a nameserver can cause named(8) to crash, leading to a denial of service. All recursive BIND DNS servers are vulnerable to this. Authoritative servers are only vulnerable if the attacker is able to control a delegation traversed by the authoritative server in order to serve the zone. III. Impact An attacker who can cause specific queries to be sent to a nameserver could cause named(8) to crash, resulting in a denial of service. IV. Workaround No workaround is available, but hosts not running named(8) 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.

I. Background The standard I/O library provides a simple and efficient buffered stream I/O interface. The library writes buffered data when it is full or when the application explicitly request so by calling the fflush(3) function. II. Problem Description A programming error in the standard I/O library's __sflush() function could erroneously adjust the buffered stream's internal state even when no write actually occurred in the case when write(2) system call returns an error. III. Impact The accounting mismatch would accumulate, if the caller does not check for stream status and will eventually lead to a heap buffer overflow. Such overflows may lead to data corruption or the execution of arbitrary code at the privilege level of the calling program. 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. 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 http://security.FreeBSD.org/patches/SA-14:27/stdio.patch # fetch http://security.FreeBSD.org/patches/SA-14:27/stdio.patch.asc # gpg --verify stdio.patch.asc b) Apply the patch.
