{"id":"CVE-2017-15124","details":"VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A malicious remote VNC client could use this flaw to cause DoS to the server host.","modified":"2026-04-02T00:04:03.587924Z","published":"2018-01-09T21:29:00.343Z","related":["SUSE-SU-2018:0762-1","SUSE-SU-2018:0831-1"],"references":[{"type":"WEB","url":"https://usn.ubuntu.com/3575-1/"},{"type":"WEB","url":"http://www.securityfocus.com/bid/102295"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:1104"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:1113"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:3062"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4213"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2018:0816"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1525195"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/qemu/qemu","events":[{"introduced":"0"},{"last_affected":"0a0dc59d27527b78a195c2d838d28b7b49e5a639"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"2.11.0"}]}}],"versions":["release_0_10_0","release_0_10_1","release_0_10_2","release_0_5_1","release_0_6_0","release_0_6_1","release_0_7_0","release_0_7_1","release_0_8_1","release_0_8_2","release_0_9_0","release_0_9_1","v0.1.0","v0.1.1","v0.1.3","v0.1.4","v0.1.5","v0.1.6","v0.10.0","v0.10.1","v0.10.2","v0.10.3","v0.10.4","v0.10.5","v0.10.6","v0.11.0","v0.11.0-rc0","v0.11.0-rc1","v0.11.0-rc2","v0.11.1","v0.12.0","v0.12.0-rc0","v0.12.0-rc1","v0.12.0-rc2","v0.12.1","v0.12.2","v0.12.3","v0.12.4","v0.12.5","v0.13.0","v0.13.0-rc0","v0.13.0-rc1","v0.13.0-rc2","v0.13.0-rc3","v0.14.0","v0.14.0-rc0","v0.14.0-rc1","v0.14.0-rc2","v0.14.1","v0.15.0","v0.15.0-rc0","v0.15.0-rc1","v0.15.0-rc2","v0.15.1","v0.2.0","v0.3.0","v0.4.0","v0.4.1","v0.4.2","v0.4.3","v0.4.4","v0.5.0","v0.5.1","v0.6.0","v0.6.1","v0.7.0","v0.7.1","v0.8.1","v0.8.2","v0.9.0","v0.9.1","v1.0","v1.0-rc0","v1.0-rc1","v1.0-rc2","v1.0-rc3","v1.0-rc4","v1.0.1","v1.1-rc0","v1.1-rc1","v1.1-rc2","v1.1.0","v1.1.0-rc2","v1.1.0-rc3","v1.1.0-rc4","v1.1.1","v1.1.2","v1.2.0","v1.2.0-rc0","v1.2.0-rc1","v1.2.0-rc2","v1.2.0-rc3","v1.2.1","v1.2.2","v1.3.0","v1.3.0-rc0","v1.3.0-rc1","v1.3.0-rc2","v1.3.1","v1.4.0","v1.4.0-rc0","v1.4.0-rc1","v1.4.0-rc2","v1.4.1","v1.4.2","v1.5.0","v1.5.0-rc0","v1.5.0-rc1","v1.5.0-rc2","v1.5.0-rc3","v1.5.1","v1.5.2","v1.5.3","v1.6.0","v1.6.0-rc0","v1.6.0-rc1","v1.6.0-rc2","v1.6.0-rc3","v1.6.1","v1.6.2","v1.7.0","v1.7.0-rc0","v1.7.0-rc1","v1.7.0-rc2","v1.7.1","v1.7.2","v2.0.0","v2.0.0-rc0","v2.0.0-rc1","v2.0.0-rc2","v2.0.0-rc3","v2.0.1","v2.0.2","v2.1.0","v2.1.0-rc0","v2.1.0-rc1","v2.1.0-rc2","v2.1.0-rc3","v2.1.0-rc4","v2.1.0-rc5","v2.1.1","v2.1.2","v2.1.3","v2.10.0","v2.10.0-rc0","v2.10.0-rc1","v2.10.0-rc2","v2.10.0-rc3","v2.10.0-rc4","v2.10.1","v2.10.2","v2.11.0","v2.11.0-rc0","v2.11.0-rc1","v2.11.0-rc2","v2.11.0-rc3","v2.11.0-rc4","v2.11.0-rc5","v2.2.0","v2.2.0-rc0","v2.2.0-rc1","v2.2.0-rc2","v2.2.0-rc3","v2.2.0-rc4","v2.2.0-rc5","v2.2.1","v2.3.0","v2.3.0-rc0","v2.3.0-rc1","v2.3.0-rc2","v2.3.0-rc3","v2.3.0-rc4","v2.3.1","v2.4.0","v2.4.0-rc0","v2.4.0-rc1","v2.4.0-rc2","v2.4.0-rc3","v2.4.0-rc4","v2.4.0.1","v2.4.1","v2.5.0","v2.5.0-rc0","v2.5.0-rc1","v2.5.0-rc2","v2.5.0-rc3","v2.5.0-rc4","v2.5.1","v2.5.1.1","v2.6.0","v2.6.0-rc0","v2.6.0-rc1","v2.6.0-rc2","v2.6.0-rc3","v2.6.0-rc4","v2.6.0-rc5","v2.6.1","v2.6.2","v2.7.0","v2.7.0-rc0","v2.7.0-rc1","v2.7.0-rc2","v2.7.0-rc3","v2.7.0-rc4","v2.7.0-rc5","v2.7.1","v2.8.0","v2.8.0-rc0","v2.8.0-rc1","v2.8.0-rc2","v2.8.0-rc3","v2.8.0-rc4","v2.8.1","v2.8.1.1","v2.9.0","v2.9.0-rc0","v2.9.0-rc1","v2.9.0-rc2","v2.9.0-rc3","v2.9.0-rc4","v2.9.0-rc5","v2.9.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-15124.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
