| 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-2006-6165 | 2 Freebsd, Netbsd | 2 Freebsd, Netbsd | 2025-01-17 | 7.2 HIGH | N/A |
| ld.so in FreeBSD, NetBSD, and possibly other BSD distributions does not remove certain harmful environment variables, which allows local users to gain privileges by passing certain environment variables to loading processes. NOTE: this issue has been disputed by a third party, stating that it is the responsibility of the application to properly sanitize the environment | |||||
| CVE-2006-0054 | 1 Freebsd | 1 Freebsd | 2025-01-16 | 5.0 MEDIUM | N/A |
| 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-2002-0391 | 4 Freebsd, Microsoft, Openbsd and 1 more | 7 Freebsd, Windows 2000, Windows Nt and 4 more | 2025-01-16 | 10.0 HIGH | 9.8 CRITICAL |
| Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd. | |||||
| CVE-2004-0079 | 23 4d, Apple, Avaya and 20 more | 66 Webstar, Mac Os X, Mac Os X Server and 63 more | 2025-01-16 | 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-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-2024-6760 | 1 Freebsd | 1 Freebsd | 2024-10-29 | 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. | |||||
| CVE-1999-0022 | 6 Bsdi, Freebsd, Hp and 3 more | 7 Bsd Os, Freebsd, Hp-ux and 4 more | 2024-10-29 | 7.2 HIGH | N/A |

| Integer overflow in print-bgp.c in the BGP dissector in tcpdump 3.9.6 and earlier allows remote attackers to execute arbitrary code via crafted TLVs in a BGP packet, related to an unchecked return value. | |||||
| CVE-2023-49298 | 2 Freebsd, Openzfs | 2 Freebsd, Openzfs | 2024-10-11 | N/A | 7.5 HIGH |
| OpenZFS through 2.1.13 and 2.2.x through 2.2.1, in certain scenarios involving applications that try to rely on efficient copying of file data, can replace file contents with zero-valued bytes and thus potentially disable security mechanisms. NOTE: this issue is not always security related, but can be security related in realistic situations. A possible example is cp, from a recent GNU Core Utilities (coreutils) version, when attempting to preserve a rule set for denying unauthorized access. (One might use cp when configuring access control, such as with the /etc/hosts.deny file specified in the IBM Support reference.) NOTE: this issue occurs less often in version 2.2.1, and in versions before 2.1.4, because of the default configuration in those versions. | |||||
| CVE-2024-45063 | 1 Freebsd | 1 Freebsd | 2024-09-06 | N/A | 8.8 HIGH |
| The function ctl_write_buffer incorrectly set a flag which resulted in a kernel Use-After-Free when a command finished processing. Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host. | |||||
| CVE-2024-8178 | 1 Freebsd | 1 Freebsd | 2024-09-06 | N/A | 8.8 HIGH |
| The ctl_write_buffer and ctl_read_buffer functions allocated memory to be returned to userspace, without initializing it. Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host. | |||||
| CVE-2024-45287 | 1 Freebsd | 1 Freebsd | 2024-09-06 | N/A | 7.5 HIGH |
| A malicious value of size in a structure of packed libnv can cause an integer overflow, leading to the allocation of a smaller buffer than required for the parsed data. | |||||
| CVE-2024-32668 | 1 Freebsd | 1 Freebsd | 2024-09-05 | N/A | 8.2 HIGH |
| An insufficient boundary validation in the USB code could lead to an out-of-bounds write on the heap, with data controlled by the caller. A malicious, privileged software running in a guest VM can exploit the vulnerability to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. | |||||
| CVE-2024-42416 | 1 Freebsd | 1 Freebsd | 2024-09-05 | N/A | 8.8 HIGH |
| The ctl_report_supported_opcodes function did not sufficiently validate a field provided by userspace, allowing an arbitrary write to a limited amount of kernel help memory. Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host. | |||||
| CVE-2024-43102 | 1 Freebsd | 1 Freebsd | 2024-09-05 | N/A | 10.0 CRITICAL |
| Concurrent removals of certain anonymous shared memory mappings by using the UMTX_SHM_DESTROY sub-request of UMTX_OP_SHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTX_SHM_DESTROY sub-request in parallel can panic the kernel or enable further Use-After-Free attacks, potentially including code execution or Capsicum sandbox escape. | |||||
| CVE-2024-43110 | 1 Freebsd | 1 Freebsd | 2024-09-05 | N/A | 8.8 HIGH |
| The ctl_request_sense function could expose up to three bytes of the kernel heap to userspace. Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host. | |||||
| CVE-2024-7589 | 1 Freebsd | 1 Freebsd | 2024-08-13 | 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. | |||||
