 ///  File Name: FreeBSD-SA-02:33.openssl
Description:
FreeBSD Security Advisory FreeBSD-SA-02:33 - The OpenSSL libraries contain multiple buffer overflows, including errors in the handling of the client master key in the SSL2 protocol implementation; the handling of the session ID in the SSL3 protocol; and in the handling of buffers used for representing integers in ASCII on 64-bit platforms, and overflows in the handling of ASN.1.

 ///  File Name: FreeBSD-SA-02_25.bzip2.asc
Description:
FreeBSD Security Advisory FreeBSD-SA-02:25 - When creating a file during decompression, the bzip2 utility failed to use the O_EXCL flag, potentially overwriting files without warning. In addition, the bzip2 utility did not securely create new files causing a race condition between creating the file and setting the correct permissions. This affects FreeBSD 4.4-RELEASE, 4.5-RELEASE and 4.5-STABLE.

Description:
FreeBSD-SA-00:19 - A bug in the BSD kernel allows local users to cause every process on the system to hang during exiting. An undocumented system call is incorrectly exported from the kernel without access-control checks, allowing for a denial of service attack. Kernel patch included for FreeBSD.

 ///  File Name: FreeBSD-SA-00:53.catopen
Description:
FreeBSD Security Advisory - catopen() may pose security risk for third party code. The catopen() function did not correctly bounds-check an internal buffer which could be indirectly overflowed by the setting of an environment variable. A privileged application which uses catopen() could be made to execute arbitrary code by an unprivileged local user. The catopen() and setlocale() functions could be made to use an arbitrary file as the source for localized data and message catalogs, instead of one of the system files. An attacker could create a file which is a valid locale file or message catalog but which contains special formatting characters which may allow certain badly written privileged applications to be exploited and execute arbitrary code as the privileged user. Patches are available.

Description:
FreeBSD Security Advisory FreeBSD-SA-02:43.bind - BIND 8 has two vulnerabilities. The BIND SIG Cached RR overflow allows a remote attacker to force a server with recursion enabled to execute arbitrary code with the privileges of the name server process. The BIND OPT DoS and BIND SIG Expiry Time DoS may cause a remote name server to crash.

 ///  File Name: FreeBSD-SA-01_49.telnetd.v1.1
Description:
FreeBSD Security Advisory FreeBSD-SA-01:49 - An overflowable buffer was found in the version of telnetd included with FreeBSD. Due to incorrect bounds checking of data buffered for output to the remote client, an attacker can cause the telnetd process to overflow the buffer and crash, or execute arbitrary code as the user running telnetd, usually root. A valid user account and password is not required to exploit this vulnerability, only the ability to connect to a telnetd server. The telnetd service is enabled by default on all FreeBSD installations if the 'high' security setting is not selected at install-time. This vulnerability is known to be exploitable, and is being actively exploited in the wild. All released versions of FreeBSD prior to the correction date including 3.5.1-RELEASE and 4.3-RELEASE are vulnerable to this problem.
