Astra Linux – Vulnerability in Linux
A issue was discovered in the kernel of NetBSD 7.1. An Access Point AP forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated with the AP. This could be exploited in Wi-Fi networks to launch denial-of-service attacks against connected clients, and it...
Astra Linux – Vulnerability in Linux
A issue was discovered in Xen through version 4.14.x. Some operating systems, such as Linux, FreeBSD, and NetBSD, process watch events using a single thread. If these events are received faster than the thread can handle them, they will be queued up. Since the queue is unbounded, a guest system m...
