Title
Spice-vdagent: integer overflow in udscs_write() leading to heap buffer overflow
Summary
A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation.
