Astra Linux – Vulnerability in Qemu

A bug in QEMU could cause a guest I/O operation that is normally directed to an arbitrary disk offset to be directed instead to offset 0. This could potentially overwrite the VM’s boot code. For example, this could be exploited by L2 guests who have a virtual disk vdiskL2 stored on the virtual di...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the QEMU-built-in VNC server during the processing of ClientCutText messages. A incorrect exit condition may lead to an infinite loop when inflating a zlib buffer controlled by an attacker in the inflatebuffer function. This could allow a remotely authenticated client, wh...
