CVE-2015-5239
Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.
Does this matter?
Lower severity and a low EPSS score (3.61%). Track it; it rarely justifies an emergency change on its own.
