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.
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.
The sendfile system call in FreeBSD 4.8 through 4.11 and 5 through 5.4 can transfer portions of kernel memory if a file is truncated while it is being sent, which could allow remote attackers to obtain sensitive information.
The TCP MSS (maximum segment size) functionality in netinet allows remote attackers to cause a denial of service (resource exhaustion) via (1) a low MTU, which causes a large number of small packets to be produced, or (2) via a large number of packets with a small TCP payload, which cause a large number of calls to the resource-intensive sowakeup function.
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.
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.
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.
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.
Flaw bug created to hold information about an old flaw we knew something about. For more details see the MITRE CVE description.
Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.
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.
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.
Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFODIRS.
Multiple symlink vulnerabilities in portupgrade before 200412262 in FreeBSD allow local users to (1) overwrite arbitrary files and possibly replace packages to execute arbitrary code via pkgfetch, (2) overwrite arbitrary files via temporary files when portupgrade upgrades a port or package, or (3) create arbitrary zero-byte files via the pkgdb.fixme temporary file.
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.
Kerberos 5 su (k5su) in FreeBSD 4.4 and earlier relies on the getlogin system call to determine if the user running k5su is root, which could allow a root-initiated process to regain its privileges after it has dropped them.
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 jail system call in FreeBSD 4.x before 4.10-RELEASE does not verify that an attempt to manipulate routing tables originated from a non-jailed process, which could allow local users to modify the routing table.
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.
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.
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.
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.
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.
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.
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.
