Name of the Vulnerable Software and Affected Versions QEMU (affected versions not specified)

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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
