Security update for qemu

This update for qemu fixes the following issues:

Security issues fixed:

  • CVE-2025-12464: stack-based buffer overflow in the e1000 network device operations can be exploited by a malicious guest user to crash the QEMU process on the host (bsc#1253002).
  • CVE-2025-11234: use-after-free in WebSocket handshake operations can be exploited by a malicious client with network access to the VNC WebSocket port to cause a denial-of-service (bsc#1250984).

Other updates and bugfixes:

  • [openSUSE][RPM] spec: require qemu-hw-display-virtio-gpu-pci for x86 too.
  • [openSUSE][RPM] spec: make glusterfs support conditional (bsc#1254494).
  • [openSUSE][RPM]: really fix *-virtio-gpu-pci dependency on ARM (bsc#1254286).

Описание

A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication.

Описание

A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This could lead to a buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user could use this vulnerability to crash the QEMU process on the host, resulting in a denial of service.
