Cisco IOS XE Software for Catalyst 9000 Family Wireless Controllers CAPWAP Denial of Service Vulnerabilities

Multiple vulnerabilities in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol processing of Cisco IOS XE Software for Cisco Catalyst 9000 Family Wireless Controllers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to insufficient validation of CAPWAP packets. An attacker could exploit the vulnerabilities by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to crash and reload, resulting in a DoS condition.

Junos OS and Junos OS Evolved: Receipt of malformed BGP path attributes leads to RPD crash

This is a similar, but different vulnerability than the issue reported as CVE-2024-39549. A double-free vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This double free of memory is causing an rpd crash, leading to a Denial of Service (DoS). This issue affects: Junos OS:  * from 22.4 before 22.4R3-S4. Junos OS Evolved: * from 22.4 before 22.4R3-S4-EVO.
