| CVE-1999-1314 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 2.1 LOW | N/A |
| Vulnerability in union file system in FreeBSD 2.2 and earlier, and possibly other operating systems, allows local users to cause a denial of service (system reload) via a series of certain mount_union commands. | |||||
| CVE-2006-0381 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| A logic error in the IP fragment cache functionality in pf in FreeBSD 5.3, 5.4, and 6.0, and OpenBSD, when a 'scrub fragment crop' or 'scrub fragment drop-ovl' rule is being used, allows remote attackers to cause a denial of service (crash) via crafted packets that cause a packet fragment to be inserted twice. | |||||
| CVE-1999-0796 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 7.5 HIGH | N/A |
| FreeBSD T/TCP Extensions for Transactions can be subjected to spoofing attacks. | |||||
| CVE-2006-0433 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 5.0 MEDIUM | N/A |
| Selective Acknowledgement (SACK) in FreeBSD 5.3 and 5.4 does not properly handle an incoming selective acknowledgement when there is insufficient memory, which might allow remote attackers to cause a denial of service (infinite loop). | |||||
| CVE-1999-0017 | 9 Caldera, Freebsd, Gnu and 6 more | 11 Openlinux, Freebsd, Inet and 8 more | 2025-04-03 | 7.5 HIGH | N/A |
| FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce. | |||||
| CVE-1999-0912 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 2.1 LOW | N/A |
| FreeBSD VFS cache (vfs_cache) allows local users to cause a denial of service by opening a large number of files. | |||||
| CVE-2004-0099 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 4.6 MEDIUM | N/A |
| mksnap_ffs in FreeBSD 5.1 and 5.2 only sets the snapshot flag when creating a snapshot for a file system, which causes default values for other flags to be used, possibly disabling security-critical settings and allowing a local user to bypass intended access restrictions. | |||||
| CVE-2003-0466 | 7 Apple, Freebsd, Netbsd and 4 more | 8 Mac Os X, Mac Os X Server, Freebsd and 5 more | 2025-04-03 | 10.0 HIGH | 9.8 CRITICAL |
| Off-by-one error in the fb_realpath() 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. | |||||
| CVE-2002-1667 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 2.1 LOW | N/A |
| The virtual memory management system in FreeBSD 4.5-RELEASE and earlier does not properly check the existence of a VM object during page invalidation, which allows local users to cause a denial of service (crash) by calling msync on an unaccessed memory map created with MAP_ANON and MAP_NOSYNC flags. | |||||
| CVE-2006-0905 | 2 Freebsd, Netbsd | 2 Freebsd, Netbsd | 2025-04-03 | 7.5 HIGH | N/A |
| A "programming error" in fast_ipsec in FreeBSD 4.8-RELEASE through 6.1-STABLE and NetBSD 2 through 3 does not properly update the sequence number associated with a Security Association, which allows packets to pass sequence number checks and allows remote attackers to capture IPSec packets and conduct replay attacks. | |||||
| CVE-2002-1674 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 1.2 LOW | N/A |
| 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. | |||||
| 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. | |||||
| CVE-2023-3494 | 1 Freebsd | 1 Freebsd | 2025-02-13 | N/A | 8.8 HIGH |
| The fwctl driver implements a state machine which is executed when a bhyve guest accesses certain x86 I/O ports. The interface lets the guest copy a string into a buffer resident in the bhyve process' memory. A bug in the state machine implementation can result in a buffer overflowing when copying this string. Malicious, privileged software running in a guest VM can exploit the buffer overflow to achieve code execution on the host in the bhyve userspace process, which typically runs as root, mitigated by the capabilities assigned through the Capsicum sandbox available to the bhyve process. | |||||
| CVE-2022-23086 | 1 Freebsd | 1 Freebsd | 2024-12-09 | N/A | 7.8 HIGH |
| Handlers for *_CFG_PAGE read / write ioctls in the mpr, mps, and mpt drivers allocated a buffer of a caller-specified size, but copied to it a fixed size header. Other heap content would be overwritten if the specified size was too small. Users with access to the mpr, mps or mpt device node may overwrite heap data, potentially resulting in privilege escalation. Note that the device node is only accessible to root and members of the operator group. | |||||
| CVE-2022-23084 | 1 Freebsd | 1 Freebsd | 2024-12-09 | N/A | 7.5 HIGH |
| The total size of the user-provided nmreq to nmreq_copyin() was first computed and then trusted during the copyin. This time-of-check to time-of-use bug could lead to kernel memory corruption. On systems configured to include netmap in their devfs_ruleset, a privileged process running in a jail can affect the host environment. | |||||
| CVE-2022-23085 | 1 Freebsd | 1 Freebsd | 2024-12-09 | N/A | 8.2 HIGH |
| A user-provided integer option was passed to nmreq_copyin() without checking if it would overflow. This insufficient bounds checking could lead to kernel memory corruption. On systems configured to include netmap in their devfs_ruleset, a privileged process running in a jail can affect the host environment. | |||||
| CVE-2024-7589 | 1 Freebsd | 1 Freebsd | 2024-11-21 | N/A | 8.1 HIGH |
| A signal handler in sshd(8) may call a logging function that is not async-signal-safe. The signal handler is invoked when a client does not authenticate within the LoginGraceTime seconds (120 by default). This signal handler executes in the context of the sshd(8)'s privileged code, which is not sandboxed and runs with full root privileges. This issue is another instance of the problem in CVE-2024-6387 addressed by FreeBSD-SA-24:04.openssh. The faulty code in this case is from the integration of blacklistd in OpenSSH in FreeBSD. As a result of calling functions that are not async-signal-safe in the privileged sshd(8) context, a race condition exists that a determined attacker may be able to exploit to allow an unauthenticated remote code execution as root. | |||||
| CVE-2024-6760 | 1 Freebsd | 1 Freebsd | 2024-11-21 | N/A | 7.5 HIGH |
| A logic bug in the code which disables kernel tracing for setuid programs meant that tracing was not disabled when it should have, allowing unprivileged users to trace and inspect the behavior of setuid programs. The bug may be used by an unprivileged user to read the contents of files to which they would not otherwise have access, such as the local password database. | |||||
