Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

Transmitted requests in Xen’s virtual network protocol can consist of multiple parts. Although none of them are actually useful, except for the initial part, any of these parts can be of zero length, meaning they carry no data at all. Apart from the certain initial portion of the data to be...

Astra Linux – Vulnerability in OVN

A flaw was discovered in the Open Virtual Network OVN. Specially crafted UDP packets may bypass egress access control lists ACLs in OVN installations that are configured with a logical switch equipped with DNS records. This occurs if the same switch has any egress ACLs configured. This issue can...

Astra Linux – Vulnerability in vlc

An integer overflow in the VNC module of the VideoLAN VLC Media Player, as of version 3.0.17.4, allows attackers to exploit this vulnerability by tricking users into opening a specially crafted playlist or connecting to a malicious VNC server. This can result in the crash of the VLC player or the...

Astra Linux – Vulnerability in OVN

A flaw was discovered in Open Virtual Network, where the service monitor MAC does not properly implement rate limiting. This issue could allow an attacker to cause a denial of service, even in deployments with CoPP enabled and properly configured...

Astra Linux – Vulnerability in OVN

A flaw was discovered in the Open Virtual Network OVN. In OVN clusters where BFD is used between hypervisors for high availability, an attacker can inject specially crafted BFD packets from within unprivileged workloads, including virtual machines or containers, which can trigger a denial of...

Astra Linux – Vulnerability in Qemu

An integer underflow issue was discovered in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could exploit this flaw to render QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service...
