Astra Linux – Vulnerability in Qemu

A flaw was discovered in the virtio-fs shared file system daemon virtiofsd of QEMU. The new ‘xattrmap’ option may cause the ‘security.capability’ xattr in the guest to not be dropped when writing files, potentially allowing a modified, privileged executable to be executed within the guest. In rar...

Astra Linux – Vulnerability in Linux

A issue was discovered in Linux: improper handling of VMIO|VMPFNMAP vmas in KVM can bypass RO checks and cause pages to be freed while still accessible by the VMM and guest. This allows users who have the ability to start and control a VM to read/write random pages of memory, potentially leading ...
