CVE-2001-0061 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 7.2 HIGH | N/A |
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. | |||||
CVE-1999-0022 | 6 Bsdi, Freebsd, Hp and 3 more | 7 Bsd Os, Freebsd, Hp-ux and 4 more | 2025-04-03 | 7.2 HIGH | 7.8 HIGH |
Local user gains root privileges via buffer overflow in rdist, via expstr() function. | |||||
CVE-2006-0054 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 5.0 MEDIUM | 5.3 MEDIUM |
The ipfw firewall in FreeBSD 6.0-RELEASE allows remote attackers to cause a denial of service (firewall crash) via ICMP IP fragments that match a reset, reject or unreach action, which leads to an access of an uninitialized pointer. | |||||
CVE-2004-0114 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-03 | 4.6 MEDIUM | N/A |
The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges. | |||||
CVE-2004-0125 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 7.2 HIGH | N/A |
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. | |||||
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-2001-0062 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 2.1 LOW | N/A |
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. | |||||
CVE-2003-0804 | 3 Apple, Freebsd, Openbsd | 4 Mac Os X, Mac Os X Server, Freebsd and 1 more | 2025-04-03 | 5.0 MEDIUM | N/A |
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. | |||||
CVE-1999-0322 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 2.1 LOW | N/A |
The open() function in FreeBSD allows local attackers to write to arbitrary files. | |||||
CVE-2004-0435 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 3.6 LOW | N/A |
Certain "programming errors" in the msync system call for FreeBSD 5.2.1 and earlier, and 4.10 and earlier, do not properly handle the MS_INVALIDATE operation, which leads to cache consistency problems that allow a local user to prevent certain changes to files from being committed to disk. | |||||
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-2023-3107 | 2 Freebsd, Netapp | 2 Freebsd, Clustered Data Ontap | 2025-02-13 | N/A | 7.5 HIGH |
A set of carefully crafted ipv6 packets can trigger an integer overflow in the calculation of a fragment reassembled packet's payload length field. This allows an attacker to trigger a kernel panic, resulting in a denial of service. | |||||
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-2023-48795 | 43 9bis, Apache, Apple and 40 more | 69 Kitty, Sshd, Sshj and 66 more | 2024-12-02 | N/A | 5.9 MEDIUM |
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0.10.6, libssh2 through 1.11.0, Thorn Tech SFTP Gateway before 3.4.6, Tera Term before 5.1, Paramiko before 3.4.0, jsch before 0.2.15, SFTPGo before 2.5.6, Netgate pfSense Plus through 23.09.1, Netgate pfSense CE through 2.7.2, HPN-SSH through 18.2.0, ProFTPD before 1.3.8b (and before 1.3.9rc2), ORYX CycloneSSH before 2.3.4, NetSarang XShell 7 before Build 0144, CrushFTP before 10.6.0, ConnectBot SSH library before 2.2.22, Apache MINA sshd through 2.11.0, sshj through 0.37.0, TinySSH through 20230101, trilead-ssh2 6401, LANCOM LCOS and LANconfig, FileZilla before 3.66.4, Nova before 11.8, PKIX-SSH before 14.4, SecureCRT before 9.4.3, Transmit5 before 5.10.4, Win32-OpenSSH before 9.5.0.0p1-Beta, WinSCP before 6.2.2, Bitvise SSH Server before 9.32, Bitvise SSH Client before 9.33, KiTTY through 0.76.1.13, the net-ssh gem 7.2.0 for Ruby, the mscdex ssh2 module before 1.15.0 for Node.js, the thrussh library before 0.35.1 for Rust, and the Russh crate before 0.40.2 for Rust. | |||||
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. |
