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-2024-7589 | 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. | ||||
CVE-2023-49298 | 2 Freebsd, Openzfs | 2 Freebsd, Openzfs | 2024-11-21 | 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-2022-32264 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.5 High |
sys/netinet/tcp_timer.h in FreeBSD before 7.0 contains a denial-of-service (DoS) vulnerability due to improper handling of TSopt on TCP connections. NOTE: This vulnerability only affects products that are no longer supported by the maintainer | ||||
CVE-2021-3450 | 11 Fedoraproject, Freebsd, Mcafee and 8 more | 39 Fedora, Freebsd, Web Gateway and 36 more | 2024-11-21 | 7.4 High |
The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. If a "purpose" has been configured then there is a subsequent opportunity for checks that the certificate is a valid CA. All of the named "purpose" values implemented in libcrypto perform this check. Therefore, where a purpose is set the certificate chain will still be rejected even when the strict flag has been used. A purpose is set by default in libssl client and server certificate verification routines, but it can be overridden or removed by an application. In order to be affected, an application must explicitly set the X509_V_FLAG_X509_STRICT verification flag and either not set a purpose for the certificate verification or, in the case of TLS client or server applications, override the default purpose. OpenSSL versions 1.1.1h and newer are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1h-1.1.1j). | ||||
CVE-2021-3449 | 13 Checkpoint, Debian, Fedoraproject and 10 more | 172 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 169 more | 2024-11-21 | 5.9 Medium |
An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). | ||||
CVE-2021-29632 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.5 High |
In FreeBSD 13.0-STABLE before n247428-9352de39c3dc, 12.2-STABLE before r370674, 13.0-RELEASE before p6, and 12.2-RELEASE before p12, certain conditions involving use of the highlight buffer while text is scrolling on the console, console data may overwrite data structures associated with the system console or other kernel memory. |
