| 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-2022-27674 | 4 Amd, Freebsd, Linux and 1 more | 4 Amd Uprof, Freebsd, Linux Kernel and 1 more | 2024-11-21 | 7.5 High |
| Insufficient validation in the IOCTL input/output buffer in AMD μProf may allow an attacker to bypass bounds checks potentially leading to a Windows kernel crash resulting in denial of service. | ||||
| CVE-2022-23831 | 4 Amd, Freebsd, Linux and 1 more | 4 Amd Uprof, Freebsd, Linux Kernel and 1 more | 2024-11-21 | 7.5 High |
| Insufficient validation of the IOCTL input buffer in AMD μProf may allow an attacker to send an arbitrary buffer leading to a potential Windows kernel crash resulting in denial of service. | ||||
| 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-2021-36159 | 1 Freebsd | 1 Libfetch | 2024-11-21 | 9.1 Critical |
| libfetch before 2021-07-26, as used in apk-tools, xbps, and other products, mishandles numeric strings for the FTP and HTTP protocols. The FTP passive mode implementation allows an out-of-bounds read because strtol is used to parse the relevant numbers into address bytes. It does not check if the line ends prematurely. If it does, the for-loop condition checks for the '\0' terminator one byte too late. | ||||
| 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. | ||||
| CVE-2021-29631 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.8 High |
| In FreeBSD 13.0-STABLE before n246941-20f96f215562, 12.2-STABLE before r370400, 11.4-STABLE before r370399, 13.0-RELEASE before p4, 12.2-RELEASE before p10, and 11.4-RELEASE before p13, certain VirtIO-based device models in bhyve failed to handle errors when fetching I/O descriptors. A malicious guest may cause the device model to operate on uninitialized I/O vectors leading to memory corruption, crashing of the bhyve process, and possibly arbitrary code execution in the bhyve process. | ||||
| CVE-2021-29630 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 8.1 High |
| In FreeBSD 13.0-STABLE before n246938-0729ba2f49c9, 12.2-STABLE before r370383, 11.4-STABLE before r370381, 13.0-RELEASE before p4, 12.2-RELEASE before p10, and 11.4-RELEASE before p13, the ggatec daemon does not validate the size of a response before writing it to a fixed-sized buffer allowing a malicious attacker in a privileged network position to overwrite the stack of ggatec and potentially execute arbitrary code. | ||||
| CVE-2021-29629 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.5 High |
| In FreeBSD 13.0-STABLE before n245765-bec0d2c9c841, 12.2-STABLE before r369859, 11.4-STABLE before r369866, 13.0-RELEASE before p1, 12.2-RELEASE before p7, and 11.4-RELEASE before p10, missing message validation in libradius(3) could allow malicious clients or servers to trigger denial of service in vulnerable servers or clients respectively. | ||||
| CVE-2021-29628 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.5 High |
| In FreeBSD 13.0-STABLE before n245764-876ffe28796c, 12.2-STABLE before r369857, 13.0-RELEASE before p1, and 12.2-RELEASE before p7, a system call triggering a fault could cause SMAP protections to be disabled for the duration of the system call. This weakness could be combined with other kernel bugs to craft an exploit. | ||||
| CVE-2021-29627 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 7.8 High |
| In FreeBSD 13.0-STABLE before n245050, 12.2-STABLE before r369525, 13.0-RC4 before p0, and 12.2-RELEASE before p6, listening socket accept filters implementing the accf_create callback incorrectly freed a process supplied argument string. Additional operations on the socket can lead to a double free or use after free. | ||||
| CVE-2021-29626 | 1 Freebsd | 1 Freebsd | 2024-11-21 | 5.5 Medium |
| In FreeBSD 13.0-STABLE before n245117, 12.2-STABLE before r369551, 11.4-STABLE before r369559, 13.0-RC5 before p1, 12.2-RELEASE before p6, and 11.4-RELEASE before p9, copy-on-write logic failed to invalidate shared memory page mappings between multiple processes allowing an unprivileged process to maintain a mapping after it is freed, allowing the process to read private data belonging to other processes or the kernel. | ||||
