14 Mar 2020 — grub2-bhyve, as used in FreeBSD bhyve before revision 525916 2020-02-12, does not validate the address provided as part of a memrw command (read_* or write_*) by a guest through a grub2.cfg file. This allows an untrusted guest to perform arbitrary read or write operations in the context of the grub-bhyve process, resulting in code execution as root on the host OS. grub2-bhyve, como es usado en FreeBSD bhyve anterior a revisión 525916 12-02-2020, no comprueba la dirección proporcionada como parte de un coman... • https://svnweb.freebsd.org/ports?view=revision&revision=525916 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

20 Feb 2020 — The IPv6 implementation in FreeBSD and NetBSD (unknown versions, year 2012 and earlier) allows remote attackers to cause a denial of service via a flood of ICMPv6 Neighbor Solicitation messages, a different vulnerability than CVE-2011-2393. La implementación de IPv6 en FreeBSD y NetBSD (versiones desconocidas, año 2012 y anteriores), permite a atacantes remotos causar una denegación de servicio por medio de una avalancha de mensajes ICMPv6 Neighbor Solicitation, una vulnerabilidad diferente de CVE-2011-2393... • http://www.openwall.com/lists/oss-security/2012/10/10/12 • CWE-400: Uncontrolled Resource Consumption •

16 Jan 2019 — An issue was discovered in OpenSSH 7.9. Due to the scp implementation being derived from 1983 rcp, the server chooses which files/directories are sent to the client. However, the scp client only performs cursory validation of the object name returned (only directory traversal attacks are prevented). A malicious scp server (or Man-in-The-Middle attacker) can overwrite arbitrary files in the scp client target directory. If recursive operation (-r) is performed, the server can manipulate subdirectories as well... • https://packetstorm.news/files/id/151227 • CWE-20: Improper Input Validation CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

04 Dec 2018 — In FreeBSD before 11.2-STABLE(r341486) and 11.2-RELEASE-p6, insufficient bounds checking in one of the device models provided by bhyve can permit a guest operating system to overwrite memory in the bhyve host possibly permitting arbitrary code execution. A guest OS using a firmware image can cause the bhyve process to crash, or possibly execute arbitrary code on the host as root. En FreeBSD, en versiones anteriores a la 11.2-STABLE(r340854) y la 11.2-RELEASE-p5, una comprobación de límites insuficiente en u... • http://www.securityfocus.com/bid/106210 • CWE-787: Out-of-bounds Write •

28 Nov 2018 — In FreeBSD before 11.2-STABLE(r340268) and 11.2-RELEASE-p5, due to incorrectly accounting for padding on 64-bit platforms, a buffer underwrite could occur when constructing an ICMP reply packet when using a non-standard value for the net.inet.icmp.quotelen sysctl. En FreeBSD, en versiones anteriores a la 11.2-STABLE(r340268) y 11.2-RELEASE-p5, debido al recuento incorrecto de relleno en plataformas de 64 bits, podría ocurrir una subescritura de búfer al construir un paquete de respuesta ICMP al emplear un v... • http://www.securityfocus.com/bid/106052 • CWE-787: Out-of-bounds Write •
