The qleioctl function in sys/dev/qlxgbe/qlioctl.c in the kernel in FreeBSD 10 and earlier does not validate a certain size parameter, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
The qlseioctl function in sys/dev/qlxge/qlsioctl.c in the kernel in FreeBSD 10 and earlier does not validate a certain size parameter, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
The nandioctl function in sys/dev/nand/nandgeom.c in the nand driver in the kernel in FreeBSD 10 and earlier does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.
Race condition in exec in OpenBSD 4.0 and earlier, NetBSD 1.5.2 and earlier, and FreeBSD 4.4 and earlier allows local users to gain privileges by attaching a debugger to a process before the kernel has determined that the process is setuid or setgid.
FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers.
The undocumented semconfig system call in BSD freezes the state of semaphores, which allows local users to cause a denial of service of the semaphore system by using the semconfig call.
Buffer overflow in FreeBSD libmytinfo library allows local users to execute commands via a long TERMCAP environmental variable.
Buffer overflow in the huh program in the orville-write package allows local users to gain root privileges.
asmon and ascpu in FreeBSD allow local users to gain root privileges via a configuration file.
Operating systems with shared memory implementations based on BSD 4.4 code allow a user to conduct a denial of service and bypass memory limits (e.g., as specified with rlimits) using mmap or shmget to allocate memory and cause page faults.
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 VFS cache (vfscache) allows local users to cause a denial of service by opening a large number of files.
Buffer overflow in Berkeley automounter daemon (amd) logging facility provided in the Linux am-utils package and others.
A buffer overflow in lsof allows local users to obtain root privilege.
ipinput.c in BSD-derived TCP/IP implementations allows remote attackers to cause a denial of service (crash or hang) via crafted packets.
Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
telnetd in FreeBSD 4.2 and earlier, and possibly other operating systems, allows remote attackers to cause a denial of service by specifying an arbitrary large file in the TERMCAP environmental variable, which consumes resources as the server processes the file.
The setlocale function in FreeBSD 5.0 and earlier, and possibly other OSes, allows local users to read arbitrary files via the LANG environmental variable.
Buffer overflow in catopen() function in FreeBSD 5.0 and earlier, and possibly other OSes, allows local users to gain root privileges via a long environmental variable.
The catopen function in FreeBSD 5.0 and earlier, and possibly other OSes, allows local users to read arbitrary files via the LANG environmental variable.
FreeBSD 4.1.1 and earlier, and possibly other BSD-based OSes, uses an insufficient random number generator to generate initial TCP sequence numbers (ISN), which allows remote attackers to spoof TCP connections.
Multiple buffer overflows in eject on FreeBSD and possibly other OSes allows local users to gain root privileges.
Buffer overflow in the Linux binary compatibility module in FreeBSD 3.x through 5.x allows local users to gain root privileges via long filenames in the linux shadow file system.
FreeBSD 5.x, 4.x, and 3.x allows local users to cause a denial of service by executing a program with a malformed ELF image header.
libedit searches for the .editrc file in the current directory instead of the user's home directory, which may allow local users to execute arbitrary commands by installing a modified .editrc in another directory.
SGI IRIX 6.5 through 6.5.12f and possibly earlier versions, and FreeBSD 3.0, allows remote attackers to cause a denial of service via a malformed IGMP multicast packet with a small response delay.
Buffer overflows in BSD-based FTP servers allows remote attackers to execute arbitrary commands via a long pattern string containing a {} sequence, as seen in (1) gopendir, (2) glstat, (3) gstat, and (4) the glob0 buffer as used in the glob functions glob2 and glob3.
ipfw and ip6fw in FreeBSD 4.2 and earlier allows remote attackers to bypass access restrictions by setting the ECE flag in a TCP packet, which makes the packet appear to be part of an established connection.
Format string vulnerability in wrapper.c in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16 allows remote attackers with CVSROOT commit access to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in a wrapper line.
