QEMU Guest Agent Authorized Keys Symlink Privilege Escalation

QEMU Guest Agent contains a local privilege escalation vulnerability in its guest-ssh-add-authorized-keys handler. An unprivileged guest user can pre-stage symbolic links that cause root-run path-based ownership changes when an operator adds an SSH key...

qemu-kvm: qemu-guest-agent: Local privilege escalation via symlink attack in guest-ssh-add-authorized-keys

A flaw was found in the QEMU Guest Agent qga. A local unprivileged user can exploit a vulnerability in the guest-ssh-add-authorized-keys command handler by manipulating symbolic links. This can occur either through a deterministic directory-symlink bypass or a Time-of-Check to Time-of-Use TOCTOU...
