CVE-2025-0373 | 2 Freebsd, Netapp | 2 Freebsd, Ontap | 2025-02-07 | 6 Medium |
On 64-bit systems, the implementation of VOP_VPTOFH() in the cd9660, tarfs and ext2fs filesystems overflows the destination FID buffer by 4 bytes, a stack buffer overflow. A NFS server that exports a cd9660, tarfs, or ext2fs file system can be made to panic by mounting and accessing the export with an NFS client. Further exploitation (e.g., bypassing file permission checking or remote kernel code execution) is potentially possible, though this has not been demonstrated. In particular, release kernels are compiled with stack protection enabled, and some instances of the overflow are caught by this mechanism, causing a panic. | ||||
CVE-2024-45289 | 1 Freebsd | 1 Freebsd | 2025-01-10 | 7.5 High |
The fetch(3) library uses environment variables for passing certain information, including the revocation file pathname. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option. Fetch would still connect to a host presenting a certificate included in the revocation file passed to the --crl option. | ||||
CVE-2024-39281 | 1 Freebsd | 1 Freebsd | 2025-01-10 | 5.3 Medium |
The command ctl_persistent_reserve_out allows the caller to specify an arbitrary size which will be passed to the kernel's memory allocator. | ||||
CVE-2023-3326 | 1 Freebsd | 1 Freebsd | 2024-12-05 | 9.8 Critical |
pam_krb5 authenticates a user by essentially running kinit with the password, getting a ticket-granting ticket (tgt) from the Kerberos KDC (Key Distribution Center) over the network, as a way to verify the password. However, if a keytab is not provisioned on the system, pam_krb5 has no way to validate the response from the KDC, and essentially trusts the tgt provided over the network as being valid. In a non-default FreeBSD installation that leverages pam_krb5 for authentication and does not have a keytab provisioned, an attacker that is able to control both the password and the KDC responses can return a valid tgt, allowing authentication to occur for any user on the system. | ||||
CVE-2024-51566 | 1 Freebsd | 1 Freebsd | 2024-11-26 | 6.5 Medium |
The NVMe driver queue processing is vulernable to guest-induced infinite loops. | ||||
CVE-2024-51565 | 1 Freebsd | 1 Freebsd | 2024-11-26 | 6.5 Medium |
The hda driver is vulnerable to a buffer over-read from a guest-controlled value. | ||||
CVE-2024-51563 | 1 Freebsd | 1 Freebsd | 2024-11-26 | 6.5 Medium |
The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition. | ||||
CVE-2024-51562 | 1 Freebsd | 1 Freebsd | 2024-11-26 | 6.5 Medium |
The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value. | ||||
CVE-2024-6640 | 1 Freebsd | 1 Freebsd | 2024-11-26 | 6.3 Medium |
In ICMPv6 Neighbor Discovery (ND), the ID is always 0. When pf is configured to allow ND and block incoming Echo Requests, a crafted Echo Request packet after a Neighbor Solicitation (NS) can trigger an Echo Reply. The packet has to come from the same host as the NS and have a zero as identifier to match the state created by the Neighbor Discovery and allow replies to be generated. ICMPv6 packets with identifier value of zero bypass firewall rules written on the assumption that the incoming packets are going to create a state in the state table. | ||||
CVE-2024-7589 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 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 | 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-2024-6759 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 5.3 Medium |
When mounting a remote filesystem using NFS, the kernel did not sanitize remotely provided filenames for the path separator character, "/". This allows readdir(3) and related functions to return filesystem entries with names containing additional path components. The lack of validation described above gives rise to a confused deputy problem. For example, a program copying files from an NFS mount could be tricked into copying from outside the intended source directory, and/or to a location outside the intended destination directory. | ||||
CVE-2024-45288 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 8.4 High |
A missing null-termination character in the last element of an nvlist array string can lead to writing outside the allocated buffer. | ||||
CVE-2024-45287 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 9.1 Critical |
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-2024-43102 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 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-2024-41928 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 8.4 High |
Malicious 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. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. | ||||
CVE-2024-41721 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 8.1 High |
An insufficient boundary validation in the USB code could lead to an out-of-bounds read on the heap, which could potentially lead to an arbitrary write and remote code execution. | ||||
CVE-2024-32668 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 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-2023-5368 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 6.5 Medium |
On an msdosfs filesystem, the 'truncate' or 'ftruncate' system calls under certain circumstances populate the additional space in the file with unallocated data from the underlying disk device, rather than zero bytes. This may permit a user with write access to files on a msdosfs filesystem to read unintended data (e.g. from a previously deleted file). | ||||
CVE-2023-51765 | 3 Freebsd, Redhat, Sendmail | 3 Freebsd, Enterprise Linux, Sendmail | 2024-11-21 | 5.3 Medium |
sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports <LF>.<CR><LF> but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features. |
