Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFODIRS.

Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling."

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.

The arplookup function in FreeBSD 5.1 and earlier, Mac OS X before 10.2.8, and possibly other BSD-based systems, allows remote attackers on a local subnet to cause a denial of service (resource starvation and panic) via a flood of spoofed ARP requests.

Off-by-one error in the fbrealpath() function, as derived from the realpath function in BSD, may allow attackers to execute arbitrary code, as demonstrated in wu-ftpd 2.5.0 through 2.6.2 via commands that cause pathnames of length MAXPATHLEN+1 to trigger a buffer overflow, including (1) STOR, (2) RETR, (3) APPE, (4) DELE, (5) MKD, (6) RMD, (7) STOU, or (8) RNTO.

Flaw bug created to hold information about an old flaw we knew something about. For more details see the MITRE CVE description.

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.

tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.

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.

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.

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 getnameinfo function in FreeBSD 4.1.1 and earlier, and possibly other operating systems, allows a remote attacker to cause a denial of service via a long DNS hostname.

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.

Format string vulnerability in top program allows local attackers to gain root privileges via the "kill" or "renice" function.

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.

TCP Wrappers (tcpwrappers) in FreeBSD 4.1.1 through 4.3 with the PARANOID ACL option enabled does not properly check the result of a reverse DNS lookup, which could allow remote attackers to bypass intended access restrictions via DNS spoofing.

sort in FreeBSD 4.1.1 and earlier, and possibly other operating systems, uses predictable temporary file names and does not properly handle when the temporary file already exists, which causes sort to crash and possibly impacts security-sensitive scripts.

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.

inetd ident server in FreeBSD 4.x and earlier does not properly set group permissions, which allows remote attackers to read the first 16 bytes of files that are accessible by the wheel group.

procfs in FreeBSD and possibly other operating systems allows local users to cause a denial of service by calling mmap on the process' own mem file, which causes the kernel to hang.

procfs in FreeBSD and possibly other operating systems does not properly restrict access to per-process mem and ctl files, which allows local users to gain root privileges by forking a child process and executing a privileged process from the child, while the parent retains access to the child's address space.

procfs in FreeBSD and possibly other operating systems allows local users to bypass access control restrictions for a jail environment and gain additional privileges.

procfs on FreeBSD before 4.5 allows local users to cause a denial of service (kernel panic) by removing a file that the fstatfs function refers to.

Integer signedness error in several system calls for FreeBSD 4.6.1 RELEASE-p10 and earlier may allow attackers to access sensitive kernel memory via large negative values to the (1) accept, (2) getsockname, and (3) getpeername system calls, and the (4) vesa FBIOGETPALETTE ioctl.
