A wrong exit condition may lead to an infinite loop when inflating an attacker controlled zlib buffer in the `inflate_buffer` function.
MEDIUM 6.5EPSS 1.89%
Does this matter?
Lower severity and a low EPSS score (1.89%). Track it; it rarely justifies an emergency change on its own.
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.
