libreswan: Invalid IKEv1 Quick Mode ID causes restart
A NULL pointer dereference flaw was found in Libreswan when processing IKEv1 Quick Mode requests. When an IKEv1 Quick Mode connection configured with IDIPV4ADDR or IDIPV6ADDR receives an IDcr payload with IDFQDN, it triggers a NULL pointer dereference error. This flaw allows a malicious client or...
libreswan: Invalid IKEv1 repeat IKE SA delete causes crash and restart
A NULL pointer dereference vulnerability was found in the Libreswan package. When an IKEv1 ISAKMP SA Informational Exchange packet contains a Delete/Notify payload followed by further Notifies that act on the ISAKMP SA, such as a duplicated Delete/Notify message, a NULL pointer dereference on the...
The vulnerability in the implementation of IPSec protocols on the SonicOS operating system allows a attacker to trigger a Denial-of-Service attack (DoS) or execute arbitrary code.
The vulnerability of the implementation of IPSec protocols on the SonicOS operating system is related to a numerical overflow condition. Exploiting this vulnerability allows a malicious actor to trigger a Denial-of-Service attack or execute arbitrary code by sending a specially crafted IKEv2...
