Summary
CVE-2023-3255 is a cybersecurity vulnerability affecting QEMU's built-in VNC server. The issue lies within the processing of ClientCutText messages, where an incorrect exit condition in the `inflate_buffer` function may result in an infinite loop. This occurs when the function inflates an attacker-controlled zlib buffer. Consequently, a remote, authenticated client with the ability to send a clipboard to the VNC server can trigger a denial-of-service condition by exploiting this flaw.
