The access permissions for a UNIX domain socket are ignored in Solaris 2.x and SunOS 4.x, and other BSD-based operating systems before 4.4, which could allow local users to connect to the socket and possibly disrupt or control the operations of the program using that socket.
FreeBSD gdc program allows local users to modify files via a symlink attack.
The open() function in FreeBSD allows local attackers to write to arbitrary files.
KDE kppp allows local users to create a directory in an arbitrary location via the HOME environmental variable.
The ptsname function in FreeBSD 6.0 through 7.0-PRERELEASE does not properly verify that a certain portion of a device name is associated with a pty of a user who is calling the pt_chown function, which might allow local users to read data from the pty from another user.
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.
pkg_add in FreeBSD 4.2 through 4.4 creates a temporary directory with world-searchable permissions, which may allow local users to modify world-writable parts of the package during installation.
In FreeBSD 12.1-STABLE before r356089, 12.1-RELEASE before 12.1-RELEASE-p3, 11.3-STABLE before r356090, and 11.3-RELEASE before 11.3-RELEASE-p7, driver specific ioctl command handlers in the oce network driver failed to check whether the caller has sufficient privileges allowing unprivileged users to send passthrough commands to the device firmware.
In FreeBSD 12.1-STABLE before r356606 and 12.1-RELEASE before 12.1-RELEASE-p3, driver specific ioctl command handlers in the ixl network driver failed to check whether the caller has sufficient privileges allowing unprivileged users to trigger updates to the device's non-volatile memory.
The geli encryption provider 7 before r239184 on FreeBSD 10 uses a weak Master Key, which makes it easier for local users to defeat a cryptographic protection mechanism via a brute-force attack.
The rc system startup script for FreeBSD 4 through 4.5 allows local users to delete arbitrary files via a symlink attack on X Windows lock files.
