| CVE-2005-0109 | 5 Freebsd, Redhat, Sco and 2 more | 9 Freebsd, Enterprise Linux, Enterprise Linux Desktop and 6 more | 2025-04-03 | N/A |
| Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses. | ||||
| CVE-2005-0356 | 9 Alaxala, Cisco, F5 and 6 more | 76 Alaxala Networks, Agent Desktop, Aironet Ap1200 and 73 more | 2025-04-03 | N/A |
| Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old. | ||||
| CVE-2005-1399 | 1 Freebsd | 1 Freebsd | 2025-04-03 | N/A |
| FreeBSD 4.6 to 4.11 and 5.x to 5.4 uses insecure default permissions for the /dev/iir device, which allows local users to execute restricted ioctl calls to read or modify data on hardware that is controlled by the iir driver. | ||||
| CVE-2006-0381 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 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-2006-0433 | 1 Freebsd | 1 Freebsd | 2025-04-03 | 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-2006-0883 | 2 Freebsd, Openbsd | 2 Freebsd, Openssh | 2025-04-03 | N/A |
| OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting. | ||||
| CVE-2006-0905 | 2 Freebsd, Netbsd | 2 Freebsd, Netbsd | 2025-04-03 | 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-2006-1283 | 1 Freebsd | 1 Freebsd | 2025-04-03 | N/A |
| opiepasswd in One-Time Passwords in Everything (OPIE) in FreeBSD 4.10-RELEASE-p22 through 6.1-STABLE before 20060322 uses the getlogin function to determine the invoking user account, which might allow local users to configure OPIE access to the root account and possibly gain root privileges if a root shell is permitted by the configuration of the wheel group or sshd. | ||||
| CVE-2006-2654 | 1 Freebsd | 1 Freebsd | 2025-04-03 | N/A |
| Directory traversal vulnerability in smbfs smbfs on FreeBSD 4.10 up to 6.1 allows local users to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences. NOTE: this is similar to CVE-2006-1864, but this is a different implementation of smbfs, so it has a different CVE identifier. | ||||
| CVE-2000-0440 | 2 Freebsd, Netbsd | 2 Freebsd, Netbsd | 2025-04-03 | N/A |
| NetBSD 1.4.2 and earlier allows remote attackers to cause a denial of service by sending a packet with an unaligned IP timestamp option. | ||||
| CVE-2000-0489 | 3 Freebsd, Netbsd, Openbsd | 3 Freebsd, Netbsd, Openbsd | 2025-04-03 | N/A |
| FreeBSD, NetBSD, and OpenBSD allow an attacker to cause a denial of service by creating a large number of socket pairs using the socketpair function, setting a large buffer size via setsockopt, then writing large buffers. | ||||
| CVE-2022-23087 | 1 Freebsd | 1 Freebsd | 2025-03-27 | 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 | 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 | 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-2023-6660 | 1 Freebsd | 1 Freebsd | 2025-02-13 | 6.5 Medium |
| When a program running on an affected system appends data to a file via an NFS client mount, the bug can cause the NFS client to fail to copy in the data to be written but proceed as though the copy operation had succeeded. This means that the data to be written is instead replaced with whatever data had been in the packet buffer previously. Thus, an unprivileged user with access to an affected system may abuse the bug to trigger disclosure of sensitive information. In particular, the leak is limited to data previously stored in mbufs, which are used for network transmission and reception, and for certain types of inter-process communication. The bug can also be triggered unintentionally by system applications, in which case the data written by the application to an NFS mount may be corrupted. Corrupted data is written over the network to the NFS server, and thus also susceptible to being snooped by other hosts on the network. Note that the bug exists only in the NFS client; the version and implementation of the server has no effect on whether a given system is affected by the problem. | ||||
| CVE-2023-6534 | 1 Freebsd | 1 Freebsd | 2025-02-13 | 7.5 High |
| In versions of FreeBSD 14.0-RELEASE before 14-RELEASE-p2, FreeBSD 13.2-RELEASE before 13.2-RELEASE-p7 and FreeBSD 12.4-RELEASE before 12.4-RELEASE-p9, the pf(4) packet filter incorrectly validates TCP sequence numbers. This could allow a malicious actor to execute a denial-of-service attack against hosts behind the firewall. | ||||
| CVE-2023-5978 | 1 Freebsd | 1 Freebsd | 2025-02-13 | 7.5 High |
| In versions of FreeBSD 13-RELEASE before 13-RELEASE-p5, under certain circumstances the cap_net libcasper(3) service incorrectly validates that updated constraints are strictly subsets of the active constraints. When only a list of resolvable domain names was specified without setting any other limitations, an application could submit a new list of domains including include entries not previously listed. This could permit the application to resolve domain names that were previously restricted. | ||||
| CVE-2023-5941 | 1 Freebsd | 1 Freebsd | 2025-02-13 | 9.8 Critical |
| In versions of FreeBSD 12.4-RELEASE prior to 12.4-RELEASE-p7 and FreeBSD 13.2-RELEASE prior to 13.2-RELEASE-p5 the __sflush() stdio function in libc does not correctly update FILE objects' write space members for write-buffered streams when the write(2) system call returns an error. Depending on the nature of an application that calls libc's stdio functions and the presence of errors returned from the write(2) system call (or an overridden stdio write routine) a heap buffer overflow may occur. Such overflows may lead to data corruption or the execution of arbitrary code at the privilege level of the calling program. | ||||
| CVE-2023-5370 | 1 Freebsd | 1 Freebsd | 2025-02-13 | 5.5 Medium |
| On CPU 0 the check for the SMCCC workaround is called before SMCCC support has been initialized. This resulted in no speculative execution workarounds being installed on CPU 0. | ||||
| CVE-2023-5369 | 1 Freebsd | 1 Freebsd | 2025-02-13 | 7.1 High |
| Before correction, the copy_file_range system call checked only for the CAP_READ and CAP_WRITE capabilities on the input and output file descriptors, respectively. Using an offset is logically equivalent to seeking, and the system call must additionally require the CAP_SEEK capability. This incorrect privilege check enabled sandboxed processes with only read or write but no seek capability on a file descriptor to read data from or write data to an arbitrary location within the file corresponding to that file descriptor. | ||||
