16 Jul 2019 — In libssh2 before 1.9.0, kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c has an integer overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. This is related to an _libssh2_check_length mistake, and is different from the various issues fixed in 1.8.1, such as ... • https://packetstorm.news/files/id/172834 • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •

06 Aug 2018 — Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP pac... • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt • CWE-400: Uncontrolled Resource Consumption •
