https://notcve.org/view.php?id=CVE-2018-6917
In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, insufficient validation of user-provided font parameters can result in an integer overflow, leading to the use of arbitrary kernel memory as glyph data. Unprivileged users may be able to access privileged kernel data. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 y 10.3-RELEASE-p28, la validación insuficiente de parámetros de fuente proporcionados por el usuario pueden resultar en un desbordamiento de enteros que conduce al uso de memoria arbitraria del kernel como datos glyph. Los usuarios sin privilegios podrían ser capaces de acceder a datos privilegiados del kernel. • http://www.securityfocus.com/bid/103668 http://www.securitytracker.com/id/1040629 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:04.vt.asc • CWE-190: Integer Overflow or Wraparound •

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, the length field of the ipsec option header does not count the size of the option header itself, causing an infinite loop when the length is zero. This issue can allow a remote attacker who is able to send an arbitrary packet to cause the machine to crash. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 y 10.3-RELEASE-p28, el campo length de la cabecera de opción ipsec no cuenta el tamaño de la propia cabecera de opción. Esto provoca un bucle infinito cuando la longitud es cero. Este problema puede permitir que un atacante remoto que pueda enviar un paquete arbitrario haga que la máquina se cierre inesperadamente. • http://seclists.org/fulldisclosure/2019/Jun/6 http://www.securityfocus.com/bid/103666 http://www.securitytracker.com/id/1040628 https://seclists.org/bugtraq/2019/May/77 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:05.ipsec.asc https://support.apple.com/kb/HT210090 https://support.apple.com/kb/HT210091 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, due to insufficient initialization of memory copied to userland, small amounts of kernel memory may be disclosed to userland processes. Unprivileged users may be able to access small amounts privileged kernel data. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 y 10.3-RELEASE-p28, debido a la insuficiente inicialización de la memoria copiada al espacio de usuario. Los usuarios sin privilegios podrían ser capaces de acceder pequeñas cantidades de datos privilegiados del kernel. • http://www.securityfocus.com/bid/103760 https://security.FreeBSD.org/advisories/FreeBSD-EN-18:04.mem.asc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Buffer overflow in the decodearr function in ntpq in ntp 4.2.8p6 through 4.2.8p10 allows remote attackers to execute arbitrary code by leveraging an ntpq query and sending a response with a crafted array. Desbordamiento de búfer en la función decodearr en ntpq en ntp, desde la versión 4.2.8p6 hasta la 4.2.8p10, permite que atacantes remotos ejecuten código arbitrario aprovechando una consulta ntpq y enviando una respuesta con un array manipulado. • http://support.ntp.org/bin/view/Main/NtpBug3414 http://support.ntp.org/bin/view/Main/SecurityNotice#February_2018_ntp_4_2_8p11_NTP_S http://www.securityfocus.com/bid/103351 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:02.ntp.asc https://security.gentoo.org/glsa/201805-12 https://security.netapp.com/advisory/ntap-20180626-0001 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03962en_us https://usn.ubuntu.com/3707-1 https://usn • CWE-787: Out-of-bounds Write •

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p7, 10.4-STABLE, 10.4-RELEASE-p7, and 10.3-RELEASE-p28, the kernel does not properly validate IPsec packets coming from a trusted host. Additionally, a use-after-free vulnerability exists in the IPsec AH handling code. This issue could cause a system crash or other unpredictable results. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p7, 10.4-STABLE, 10.4-RELEASE-p7 y 10.3-RELEASE-p28, el kernel no valida correctamente los paquetes IPsec provenientes de un host de confianza. Además, existe una vulnerabilidad de uso de memoria previamente liberada en el código de manipulación de IPsec AH. • http://www.securitytracker.com/id/1040460 https://www.freebsd.org/security/advisories/FreeBSD-SA-18:01.ipsec.asc • CWE-416: Use After Free •
