In FreeBSD 12.1-STABLE before r361918, 12.1-RELEASE before p6, 11.4-STABLE before r361919, 11.3-RELEASE before p10, and 11.4-RC2 before p1, an invalid memory location may be used for HID items if the push/pop level is not restored within the processing of that HID item allowing an attacker with physical access to a USB port to be able to use a specially crafted USB device to gain kernel or user-space code execution. En FreeBSD versión 12.1-ESTABLE versiones anteriores a r361918, 12.1-RELEASE versiones anteriores a p6, 11.4-ESTABLE versiones anteriores a r361919, 11.3-RELEASE versiones anteriores a p10 y 11.4-RC2 versiones anteriores a p1, puede ser usada una ubicación de memoria no comprobada para elementos HID si el nivel de inserción/extracción no es restaurado dentro del procesamiento de ese elemento HID, permitiendo que un atacante con acceso físico a un puerto USB pueda usar un dispositivo USB especialmente diseñado para conseguir una ejecución de código de kernel o del espacio de usuario • https://security.FreeBSD.org/advisories/FreeBSD-SA-20:17.usb.asc https://security.netapp.com/advisory/ntap-20200625-0005 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.5EPSS: 0%CPEs: 43EXPL: 1CVE-2020-13434 – sqlite: integer overflow in sqlite3_str_vappendf function in printf.c
https://notcve.org/view.php?id=CVE-2020-13434
SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c. SQLite versiones hasta 3.32.0, presenta un desbordamiento de enteros en la función sqlite3_str_vappendf en el archivo printf.c. An integer overflow flaw was found in the SQLite implementation of the printf() function. This flaw allows an attacker who can control the precision of floating-point conversions, to crash the application, resulting in a denial of service. • http://seclists.org/fulldisclosure/2020/Dec/32 http://seclists.org/fulldisclosure/2020/Nov/19 http://seclists.org/fulldisclosure/2020/Nov/20 http://seclists.org/fulldisclosure/2020/Nov/22 https://lists.debian.org/debian-lts-announce/2020/05/msg00024.html https://lists.debian.org/debian-lts-announce/2020/08/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L7KXQWHIY2MQP4LNM6ODWJENMXYYQYBN https://security.FreeBSD.org/advisories/FreeBSD-SA-20: • CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •

In FreeBSD 12.1-STABLE before r356908, 12.1-RELEASE before p5, 11.3-STABLE before r356908, and 11.3-RELEASE before p9, a race condition in the cryptodev module permitted a data structure in the kernel to be used after it was freed, allowing an unprivileged process can overwrite arbitrary kernel memory. En FreeBSD versiones 12.1-STABLE anteriores a r352509, versiones 11.3-STABLE anteriores a r352509 y versiones 11.3-RELEASE anteriores a p9, una condición de carrera en el módulo cryptodev permitía utilizar una estructura de datos en el kernel después de liberarla, permitiendo a un proceso no privilegiado poder sobrescribir la memoria del kernel arbitrariamente. • https://security.FreeBSD.org/advisories/FreeBSD-SA-20:15.cryptodev.asc https://security.netapp.com/advisory/ntap-20200518-0005 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-772: Missing Release of Resource after Effective Lifetime •

In FreeBSD 12.1-STABLE before r352509, 11.3-STABLE before r352509, and 11.3-RELEASE before p9, an unprivileged local user can trigger a use-after-free situation due to improper checking in SCTP when an application tries to update an SCTP-AUTH shared key. En FreeBSD versiones 12.1-STABLE anteriores a r352509, versiones 11.3-STABLE anteriores a r352509 y versiones 11.3-RELEASE anteriores a p9, un usuario local no privilegiado puede desencadenar una situación de uso de la memoria previamente liberada debido a una comprobación inapropiada en SCTP cuando una aplicación intenta actualizar una clave compartida SCTP-AUTH. • https://security.FreeBSD.org/advisories/FreeBSD-SA-20:14.sctp.asc https://security.netapp.com/advisory/ntap-20200518-0007 • CWE-416: Use After Free •
CVSS: 5.5EPSS: 0%CPEs: 16EXPL: 0CVE-2020-7455 – FreeBSD Kernel NAT Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-7455
In FreeBSD 12.1-STABLE before r360973, 12.1-RELEASE before p5, 11.4-STABLE before r360973, 11.4-BETA1 before p1 and 11.3-RELEASE before p9, the FTP packet handler in libalias incorrectly calculates some packet length allowing disclosure of small amounts of kernel (for kernel NAT) or natd process space (for userspace natd). En FreeBSD versiones 12.1-STABLE anteriores a r360973, versiones 12.1-RELEASE anteriores a p5, versiones 11.4-STABLE anteriores a r360973, versiones 11.4-BETA1 anteriores a p1 y versiones 11.3-RELEASE anteriores a p9, el manejador de paquetes FTP en libalias calcula incorrectamente la longitud de algunos paquetes permitiendo divulgar pequeñas cantidades del kernel (para el kernel NAT) o espacio de proceso natd (para el espacio de usuario natd). This vulnerability allows local attackers to disclose sensitive information on affected installations of FreeBSD Kernel. Authentication is required to exploit this vulnerability. The specific flaw exists within the implementation of NAT. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. • https://security.FreeBSD.org/advisories/FreeBSD-SA-20:13.libalias.asc https://security.netapp.com/advisory/ntap-20200518-0005 https://www.zerodayinitiative.com/advisories/ZDI-20-661 • CWE-772: Missing Release of Resource after Effective Lifetime •
