Security flaws in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD)Security flaws in Cisco

We have three new vulnerabilities in Cisco.

One could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition.
One that could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system with root-level privileges. Administrator-level privileges are required to exploit this vulnerability.
And another one which could allow an authenticated, local attacker to execute arbitrary code with root-level privileges. Administrator-level privileges are required to exploit this vulnerability.

New toy in my car

I’m driving a Peugeot 308 from 2015. It’s a really nice car, but one feature is missing in it. May look silly, but I believe this is feature which increase safety at road.

Cisco IOS Software for Catalyst 6000 Series Switches Denial of Service Vulnerability

A vulnerability in Cisco IOS Software for Cisco Catalyst 6000 Series Switches could allow an unauthenticated, adjacent attacker to cause an affected device to reload unexpectedly.

This vulnerability is due to improper handling of process-switched traffic. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition.

Big changes in my home server

For a long time I was using Proxmox as my server OS. On it I had few VMs. One with Arch Linux (I’m using it as my daily OS through RDP), another one with Home Assistant, another one for media (Jellyfin app, Calibre, etc). And some created ad-hoc when needed for testing. But from some time I was thinking about big change. And finally it happened during this week.
