Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.","published":"2020-10-07T15:15:12.000Z","lastModified":"2026-06-17T02:54:37.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":6.6,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L"},"cwe":["CWE-120"],"affected":["spice project/spice","redhat/openstack","canonical/ubuntu linux","debian/debian linux","opensuse/leap","redhat/enterprise linux","redhat/enterprise linux aus","redhat/enterprise linux eus","redhat/enterprise linux tus","redhat/enterprise linux update services for sap solutions"],"epss":{"score":0.02656,"percentile":0.85564,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (2.66%).
