CVE-2004-1066 1 Freebsd 1 Freebsd 2025-04-03 3.6 LOW N/A
The cmdline pseudofiles in (1) procfs on FreeBSD 4.8 through 5.3, and (2) linprocfs on FreeBSD 5.x through 5.3, do not properly validate a process argument vector, which allows local users to cause a denial of service (panic) or read portions of kernel memory. NOTE: this candidate might be SPLIT into 2 separate items in the future.
CVE-2000-0388 1 Freebsd 1 Freebsd 2025-04-03 7.5 HIGH N/A
Buffer overflow in FreeBSD libmytinfo library allows local users to execute commands via a long TERMCAP environmental variable.
CVE-2005-1406 1 Freebsd 1 Freebsd 2025-04-03 4.6 MEDIUM N/A
The kernel in FreeBSD 4.x to 4.11 and 5.x to 5.4 does not properly clear certain fixed-length buffers when copying variable-length data for use by applications, which could allow those applications to read previously used sensitive memory.
CVE-2002-0973 1 Freebsd 1 Freebsd 2025-04-03 4.6 MEDIUM N/A
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 FBIO_GETPALETTE ioctl.
CVE-2002-0572 3 Freebsd, Openbsd, Sun 4 Freebsd, Openbsd, Solaris and 1 more 2025-04-03 7.2 HIGH N/A
FreeBSD 4.5 and earlier, and possibly other BSD-based operating systems, allows local users to write to or read from restricted files by closing the file descriptors 0 (standard input), 1 (standard output), or 2 (standard error), which may then be reused by a called setuid process that intended to perform I/O on normal files.
CVE-2003-0001 4 Freebsd, Linux, Microsoft and 1 more 5 Freebsd, Linux Kernel, Windows 2000 and 2 more 2025-04-03 5.0 MEDIUM N/A
Multiple ethernet Network Interface Card (NIC) device drivers do not pad frames with null bytes, which allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets, as demonstrated by Etherleak.
CVE-2000-0993 3 Freebsd, Netbsd, Openbsd 3 Freebsd, Netbsd, Openbsd 2025-04-03 7.2 HIGH N/A
Format string vulnerability in pw_error function in BSD libutil library allows local users to gain root privileges via a malformed password in commands such as chpass or passwd.
CVE-1999-0131 8 Bsdi, Digital, Eric Allman and 5 more 9 Bsd Os, Osf 1, Sendmail and 6 more 2025-04-03 7.2 HIGH N/A
Buffer overflow and denial of service in Sendmail 8.7.5 and earlier through GECOS field gives root access to local users.
CVE-2003-0914 9 Compaq, Freebsd, Hp and 6 more 10 Tru64, Freebsd, Hp-ux and 7 more 2025-04-03 4.3 MEDIUM N/A
ISC BIND 8.3.x before 8.3.7, and 8.4.x before 8.4.3, allows remote attackers to poison the cache via a malicious name server that returns negative responses with a large TTL (time-to-live) value.
CVE-2001-1166 1 Freebsd 1 Freebsd 2025-04-03 5.0 MEDIUM N/A
linprocfs on FreeBSD 4.3 and earlier does not properly restrict access to kernel memory, which allows one process with debugging rights on a privileged process to read restricted memory from that process.
CVE-2002-0755 1 Freebsd 1 Freebsd 2025-04-03 7.2 HIGH N/A
Kerberos 5 su (k5su) in FreeBSD 4.5 and earlier does not verify that a user is a member of the wheel group before granting superuser privileges, which could allow unauthorized users to execute commands as root.
CVE-2004-0079 23 4d, Apple, Avaya and 20 more 66 Webstar, Mac Os X, Mac Os X Server and 63 more 2025-04-03 5.0 MEDIUM 7.5 HIGH
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
CVE-2003-1230 1 Freebsd 1 Freebsd 2025-04-03 6.4 MEDIUM N/A
The implementation of SYN cookies (syncookies) in FreeBSD 4.5 through 5.0-RELEASE-p3 uses only 32-bit internal keys when generating syncookies, which makes it easier for remote attackers to conduct brute force ISN guessing attacks and spoof legitimate traffic.
CVE-2000-0440 2 Freebsd, Netbsd 2 Freebsd, Netbsd 2025-04-03 5.0 MEDIUM N/A
NetBSD 1.4.2 and earlier allows remote attackers to cause a denial of service by sending a packet with an unaligned IP timestamp option.
CVE-2001-0183 1 Freebsd 1 Freebsd 2025-04-03 7.5 HIGH N/A
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.
CVE-2003-0688 6 Compaq, Freebsd, Openbsd and 3 more 6 Tru64, Freebsd, Openbsd and 3 more 2025-04-03 5.0 MEDIUM N/A
The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.
CVE-1999-0023 6 Bsdi, Freebsd, Ibm and 3 more 10 Bsd Os, Freebsd, Aix and 7 more 2025-04-03 7.2 HIGH N/A
Local user gains root privileges via buffer overflow in rdist, via lookup() function.
CVE-2022-23087 1 Freebsd 1 Freebsd 2025-03-27 N/A 8.8 HIGH
The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets. When checksum offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to specify the checksum offset in the on-stack buffer. The offset was not validated for certain packet types. A misbehaving bhyve guest could overwrite memory in the bhyve process on the host, possibly leading to code execution in the host context. The bhyve process runs in a Capsicum sandbox, which (depending on the FreeBSD version and bhyve configuration) limits the impact of exploiting this issue.
CVE-2023-0751 1 Freebsd 1 Freebsd 2025-03-25 N/A 6.5 MEDIUM
When GELI reads a key file from standard input, it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase, the master key is encrypted with an empty key file allowing trivial recovery of the master key.
CVE-2023-4809 1 Freebsd 1 Freebsd 2025-02-13 N/A 7.5 HIGH
In pf packet processing with a 'scrub fragment reassemble' rule, a packet containing multiple IPv6 fragment headers would be reassembled, and then immediately processed. That is, a packet with multiple fragment extension headers would not be recognized as the correct ultimate payload. Instead a packet with multiple IPv6 fragment headers would unexpectedly be interpreted as a fragmented packet, rather than as whatever the real payload is. As a result, IPv6 fragments may bypass pf firewall rules written on the assumption all fragments have been reassembled and, as a result, be forwarded or processed by the host.
