FreeBSD Security Advisory FreeBSD-SA-06:16.smbfs: smbfs does not properly sanitize paths containing a backslash character; in particular the directory name '..\' is interpreted as the parent directory by the SMB/CIFS server, but smbfs handles it in the same manner as any other directory.

FreeBSD-SA-06-15.ypserv.txt |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-06:15.ypserv: There are two documented methods of restricting access to NIS maps through ypserv(8): through the use of the /var/yp/securenets file, and through the /etc/hosts.allow file. While both mechanisms are implemented in the server, a change in the build process caused the "securenets" access restrictions to be inadvertently disabled.

FreeBSD-SA-06-12.opie.txt |
Description:
|
FreeBSD-SA-06:12.opie - The opiepasswd(1) program uses getlogin(2) to identify the user calling opiepasswd(1). In some circumstances getlogin(2) will return "root" even when running as an unprivileged user. This causes opiepasswd(1) to allow an unpriviled user to configure OPIE authentication for the root user.

Description:
|
FreeBSD Security Advisory FreeBSD-SA-03:01 - It has been found that the CVS server can be tricked to free memory more then once, which can be used for remote code execution. Additionally, the CVS server allowed clients with write access to specify arbitrary commands to execute as part of an update (update-prog) or commit (checkin-prog). This behavior has been restricted. This affects all FreeBSD versions prior to 4.6-RELEASE-p7, 4.7-RELEASE-p4 and 5.0-RELEASE-p1.

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.
