| CVE-2018-17155 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| In FreeBSD before 11.2-STABLE(r338983), 11.2-RELEASE-p4, 11.1-RELEASE-p15, 10.4-STABLE(r338984), and 10.4-RELEASE-p13, due to insufficient initialization of memory copied to userland in the getcontext and swapcontext system calls, small amounts of kernel memory may be disclosed to userland processes. Unprivileged authenticated local users may be able to access small amounts privileged kernel data. | ||||
| CVE-2009-4358 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| freebsd-update in FreeBSD 8.0, 7.2, 7.1, 6.4, and 6.3 uses insecure permissions in its working directory (/var/db/freebsd-update by default), which allows local users to read copies of sensitive files after a (1) freebsd-update fetch (fetch) or (2) freebsd-update upgrade (upgrade) operation. | ||||
| CVE-2005-1400 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| The i386_get_ldt system call in FreeBSD 4.7 to 4.11 and 5.x to 5.4 allows local users to access sensitive kernel memory via arguments with negative or very large values. | ||||
| CVE-2005-1036 | 2 Amd, Freebsd | 2 Amd64, Freebsd | 2024-09-16 | 7.8 High |
| FreeBSD 5.x to 5.4 on AMD64 does not properly initialize the IO permission bitmap used to allow user access to certain hardware, which allows local users to bypass intended access restrictions to cause a denial of service, obtain sensitive information, and possibly gain privileges. | ||||
| CVE-2006-5482 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| ufs_vnops.c in FreeBSD 6.1 allows local users to cause an unspecified denial of service by calling the ftruncate function on a file type that is not VREG, VLNK or VDIR, which is not defined in POSIX. | ||||
| CVE-2018-6922 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| One of the data structures that holds TCP segments in all versions of FreeBSD prior to 11.2-RELEASE-p1, 11.1-RELEASE-p12, and 10.4-RELEASE-p10 uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the number of segments in the reassembly queue. An attacker who has the ability to send TCP traffic to a victim system can degrade the victim system's network performance and/or consume excessive CPU by exploiting the inefficiency of TCP reassembly handling, with relatively small bandwidth cost. | ||||
| CVE-2010-2693 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| FreeBSD 7.1 through 8.1-PRERELEASE does not copy the read-only flag when creating a duplicate mbuf buffer reference, which allows local users to cause a denial of service (system file corruption) and gain privileges via the sendfile system call. | ||||
| CVE-2012-3549 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| The SCTP implementation in FreeBSD 8.2 allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted ASCONF chunk. | ||||
| CVE-2005-2068 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| FreeBSD 4.x through 4.11 and 5.x through 5.4 allows remote attackers to modify certain TCP options via a TCP packet with the SYN flag set for an already established session. | ||||
| CVE-2018-6920 | 1 Freebsd | 1 Freebsd | 2024-09-16 | N/A |
| In FreeBSD before 11.1-STABLE(r332303), 11.1-RELEASE-p10, 10.4-STABLE(r332321), and 10.4-RELEASE-p9, due to insufficient initialization of memory copied to userland in the Linux subsystem and Atheros wireless driver, small amounts of kernel memory may be disclosed to userland processes. Unprivileged authenticated local users may be able to access small amounts of privileged kernel data. | ||||
| CVE-2024-6387 | 9 Amazon, Canonical, Debian and 6 more | 24 Linux 2023, Ubuntu Linux, Debian Linux and 21 more | 2024-09-14 | 8.1 High |
| A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. | ||||
| CVE-2024-8178 | 1 Freebsd | 1 Freebsd | 2024-09-06 | 9.3 Critical |
| 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-2024-45063 | 1 Freebsd | 1 Freebsd | 2024-09-06 | 9.8 Critical |
| 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-2024-42416 | 1 Freebsd | 1 Freebsd | 2024-09-05 | 8.4 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-2024-43110 | 1 Freebsd | 1 Freebsd | 2024-09-05 | 8.4 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 | 2024-08-16 | 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-2024-6759 | 1 Freebsd | 1 Freebsd | 2024-08-16 | 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-2000-1167 | 1 Freebsd | 1 Freebsd | 2024-08-08 | N/A |
| ppp utility in FreeBSD 4.1.1 and earlier does not properly restrict access as specified by the "nat deny_incoming" command, which allows remote attackers to connect to the target system. | ||||
| CVE-2000-1184 | 1 Freebsd | 1 Freebsd | 2024-08-08 | N/A |
| telnetd in FreeBSD 4.2 and earlier, and possibly other operating systems, allows remote attackers to cause a denial of service by specifying an arbitrary large file in the TERMCAP environmental variable, which consumes resources as the server processes the file. | ||||
| CVE-2000-1066 | 1 Freebsd | 1 Freebsd | 2024-08-08 | N/A |
| The getnameinfo function in FreeBSD 4.1.1 and earlier, and possibly other operating systems, allows a remote attacker to cause a denial of service via a long DNS hostname. | ||||
