Description

A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. A wrong exit condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the `inflate_buffer` function. This could allow a remote authenticated client who is able to send a clipboard to the VNC server to trigger a denial of service.

Affected configurations

• qemu qemu (<= 8.0.3) • redhat enterprise linux 8.0 • redhat enterprise linux 9.0 • fedoraproject fedora 38
