Уязвимость модуля Apache для усиления безопасности веб-приложений modsecurity-apache, связанная с ошибками при обработке JSON-объектов, позволяющая нарушителю вызвать отказ в обслуживании

ModSecurity 3.x through 3.0.5 mishandles excessively nested JSON objects. Crafted JSON objects with nesting tens-of-thousands deep could result in the web server being unable to service legitimate requests. Even a moderately large (e.g., 300KB) HTTP request can occupy one of the limited NGINX worker processes for minutes and consume almost all of the available CPU on the machine. Modsecurity 2 is similarly vulnerable: the affected versions include 2.8.0 through 2.9.4.

In ModSecurity before 2.9.6 and 3.x before 3.0.8, HTTP multipart requests were incorrectly parsed and could bypass the Web Application Firewall. NOTE: this is related to CVE-2022-39956 but can be considered independent changes to the ModSecurity (C language) codebase.

Уязвимость драйвера mlx5 набора библиотек и драйверов для быстрой обработки пакетов dpdk, позволяющая науршителю вызвать отказ в обслуживании

A permissive list of allowed inputs flaw was found in DPDK. This issue allows a remote attacker to cause a denial of service triggered by sending a crafted Vhost header to DPDK.

NVIDIA’s distribution of the Data Plane Development Kit (MLNX_DPDK) contains a vulnerability in the network stack, where error recovery is not handled properly, which can allow a remote attacker to cause denial of service and some impact to data integrity and confidentiality.

Уязвимость программного многоуровневого коммутатора Open vSwitch, связанная с потерей значимости целого числа, позволяющая нарушителю выполнить произвольный код в целевой системе

Уязвимость программного многоуровневого коммутатора OpenvSwitch, связанная с реализацией некорректного потока управления, позволяющая нарушителю получить доступ к конфиденциальным данным, а также вызвать отказ в обслуживании

The TSS (Tuple Space Search) algorithm in Open vSwitch 2.x through 2.17.2 and 3.0.0 allows remote attackers to cause a denial of service (delays of legitimate traffic) via crafted packet data that requires excessive evaluation time within the packet classification algorithm for the MegaFlow cache, aka a Tuple Space Explosion (TSE) attack.

A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.

An out-of-bounds read in Organization Specific TLV was found in various versions of OpenvSwitch.

An integer underflow in Organization Specific TLV was found in various versions of OpenvSwitch.

A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow.
