23 Mar 2006 — opiepasswd in One-Time Passwords in Everything (OPIE) in FreeBSD 4.10-RELEASE-p22 through 6.1-STABLE before 20060322 uses the getlogin function to determine the invoking user account, which might allow local users to configure OPIE access to the root account and possibly gain root privileges if a root shell is permitted by the configuration of the wheel group or sshd.

23 Mar 2006 — A "programming error" in fast_ipsec in FreeBSD 4.8-RELEASE through 6.1-STABLE and NetBSD 2 through 3 does not properly update the sequence number associated with a Security Association, which allows packets to pass sequence number checks and allows remote attackers to capture IPSec packets and conduct replay attacks. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:11.ipsec.asc •

11 Jan 2006 — The ispell_op function in ee on FreeBSD 4.10 to 6.0 uses predictable filenames and does not confirm which file is being written, which allows local users to overwrite arbitrary files via a symlink attack when ee invokes ispell. The ispell_op function used by ee(1) while executing spell check operations employs an insecure method of temporary file generation. This method produces predictable file names based on the process ID and fails to confirm which path will be over written with the user. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-06:02.ee.asc •

31 Dec 2005 — The securelevels implementation in FreeBSD 7.0 and earlier, OpenBSD up to 3.8, DragonFly up to 1.2, and Linux up to 2.6.15 allows root users to bypass immutable settings for files by mounting another filesystem that masks the immutable files while the system is running. • https://packetstorm.news/files/id/42925 •

21 Jul 2005 — The device file system (devfs) in FreeBSD 5.x does not properly check parameters of the node type when creating a device node, which makes hidden devices available to attackers, who can then bypass restrictions on a jailed process. El sistema de ficheros de dispositivos en FreeBSD 5.x no comprueba adecuadamente los parámetros del tipo de nodo cuando crea un nodo de dispositivo, lo que hace que dispositivos ocultos estén disponibles a tacantes (quienes pueden por tanto sortear restricciones en ciertos proces... • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:17.devfs.asc •

30 Jun 2005 — FreeBSD 4.x through 4.11 and 5.x through 5.4 allows remote attackers to modify certain TCP options via a TCP packet with the SYN flag set for an already established session. • ftp://ftp.freebsd.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:15.tcp.asc •

31 May 2005 — Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. • https://www.exploit-db.com/exploits/1008 •

06 May 2005 — The i386_get_ldt system call in FreeBSD 4.7 to 4.11 and 5.x to 5.4 allows local users to access sensitive kernel memory via arguments with negative or very large values. The i386_get_ldt(2) system call allows a process to request that a portion of its Local Descriptor Table be copied from the kernel into userland. The i386_get_ldt(2) syscall performs insufficient validation of its input arguments. In particular, negative or very large values may allow inappropriate data to be copied from the kernel. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:07.ldt.asc •

06 May 2005 — FreeBSD 4.6 to 4.11 and 5.x to 5.4 uses insecure default permissions for the /dev/iir device, which allows local users to execute restricted ioctl calls to read or modify data on hardware that is controlled by the iir driver. The default permissions on the /dev/iir device node allow unprivileged local users to open the device and execute ioctl calls. Unprivileged local users can send commands to the hardware supported by the iir(4) driver, allowing destruction of data and possible disclosure of data. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:06.iir.asc •

06 May 2005 — The kernel in FreeBSD 4.x to 4.11 and 5.x to 5.4 does not properly clear certain fixed-length buffers when copying variable-length data for use by applications, which could allow those applications to read previously used sensitive memory. In many parts of the FreeBSD kernel, names (of mount points, devices, files, etc.) are manipulated as NULL-terminated strings, but are provided to applications within fixed-length buffers. • ftp://ftp.FreeBSD.org/pub/FreeBSD/CERT/advisories/FreeBSD-SA-05:08.kmem.asc •
