{"id":"CVE-2019-15681","details":"LibVNC commit before d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a contains a memory leak (CWE-655) in VNC server code, which allow an attacker to read stack memory and can be abused for information disclosure. Combined with another vulnerability, it can be used to leak stack memory and bypass ASLR. This attack appear to be exploitable via network connectivity. These vulnerabilities have been fixed in commit d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a.","modified":"2026-04-16T00:00:56.229485306Z","published":"2019-10-29T19:15:18.127Z","related":["SUSE-SU-2020:0955-1","SUSE-SU-2020:1164-1","SUSE-SU-2020:1164-2","SUSE-SU-2020:1165-1","SUSE-SU-2020:14355-1","SUSE-SU-2020:2009-1","openSUSE-SU-2020:0624-1","openSUSE-SU-2020:1071-1","openSUSE-SU-2024:10598-1","openSUSE-SU-2024:11498-1"],"database_specific":{"unresolved_ranges":[{"extracted_events":[{"last_affected":"14.04"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:lts:*:*:*"},{"extracted_events":[{"last_affected":"16.04"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:esm:*:*:*"},{"extracted_events":[{"last_affected":"16.04"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*"},{"extracted_events":[{"last_affected":"18.04"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*"},{"extracted_events":[{"last_affected":"18.10"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:canonical:ubuntu_linux:18.10:*:*:*:*:*:*:*"},{"extracted_events":[{"last_affected":"8.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*"},{"extracted_events":[{"last_affected":"9.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"},{"extracted_events":[{"introduced":"3.0.0.0"},{"fixed":"3.2.1.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:siemens:simatic_itc1500_firmware:*:*:*:*:*:*:*:*"},{"extracted_events":[{"introduced":"3.0.0.0"},{"fixed":"3.2.1.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:siemens:simatic_itc1500_pro_firmware:*:*:*:*:*:*:*:*"},{"extracted_events":[{"introduced":"3.0.0.0"},{"fixed":"3.2.1.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:siemens:simatic_itc1900_firmware:*:*:*:*:*:*:*:*"},{"extracted_events":[{"introduced":"3.0.0.0"},{"fixed":"3.2.1.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:siemens:simatic_itc1900_pro_firmware:*:*:*:*:*:*:*:*"},{"extracted_events":[{"introduced":"3.0.0.0"},{"fixed":"3.2.1.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:siemens:simatic_itc2200_firmware:*:*:*:*:*:*:*:*"},{"extracted_events":[{"introduced":"3.0.0.0"},{"fixed":"3.2.1.0"}],"source":"CPE_FIELD","cpe":"cpe:2.3:o:siemens:simatic_itc2200_pro_firmware:*:*:*:*:*:*:*:*"}]},"references":[{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00027.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00073.html"},{"type":"ADVISORY","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-390195.pdf"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/10/msg00039.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/10/msg00042.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/11/msg00032.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/12/msg00028.html"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4407-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4547-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4573-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4587-1/"},{"type":"FIX","url":"https://github.com/LibVNC/libvncserver/commit/d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/libvnc/libvncserver","events":[{"introduced":"0"},{"fixed":"0a70095271d845d16a3ed17354841b01f33963ad"},{"fixed":"d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.9.12"}],"source":["CPE_FIELD","REFERENCES"],"cpe":"cpe:2.3:a:libvnc_project:libvncserver:*:*:*:*:*:*:*:*"}}],"versions":["LibVNCServer-0.9.10","LibVNCServer-0.9.11","LibVNCServer-0.9.12","LibVNCServer-0.9.8","LibVNCServer-0.9.9","X11VNC_0_9_10","X11VNC_0_9_11","X11VNC_0_9_12","X11VNC_0_9_7","X11VNC_0_9_8","X11VNC_0_9_9","X11VNC_REL_0_9_4","X11VNC_REL_0_9_5","X11VNC_REL_0_9_6"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-15681.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
