NOTE: this vulnerability exists because an incomplete fix for CVE-2007-1320. | It was found that the Cirrus blit region checks were insufficient. A privileged guest user could use this flaw to write outside of VRAM-allocated buffer boundaries in the host's QEMU process address space with attacker-provided data. | Description | updated |
