{"id":"UBUNTU-CVE-2018-6548","details":"A use-after-free issue was discovered in libwebm through 2018-02-02. If a Vp9HeaderParser was initialized once before, its property frame_ would not be changed because of code in vp9parser::Vp9HeaderParser::SetFrame. Its frame_ could be freed while the corresponding pointer would not be updated, leading to a dangling pointer. This is related to the function OutputCluster in webm_info.cc.","modified":"2026-04-22T12:02:23.503322Z","published":"2018-02-02T09:29:00Z","upstream":["CVE-2018-6548"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-6548"},{"type":"REPORT","url":"https://github.com/dwfault/PoCs/blob/master/libwebm%20Vp9HeaderParser%20UAF%20by%20PrintVP9Info/libwebm%20Vp9HeaderParser%20UAF%20by%20PrintVP9Info.md"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-6548"}],"affected":[{"package":{"name":"oxide-qt","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/oxide-qt@1.21.5-0ubuntu0.16.04.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.9.5-0ubuntu1","1.10.3-0ubuntu0.15.10.1","1.10.3-0ubuntu0.15.10.2","1.11.3-0ubuntu3","1.11.4-0ubuntu1","1.11.5-0ubuntu1","1.12.5-0ubuntu1","1.12.6-0ubuntu1","1.12.7-0ubuntu1","1.13.6-0ubuntu1","1.14.7-0ubuntu1","1.14.9-0ubuntu0.16.04.1","1.15.7-0ubuntu0.16.04.1","1.15.8-0ubuntu0.16.04.1","1.16.5-0ubuntu0.16.04.1","1.17.7-0ubuntu0.16.04.1","1.17.9-0ubuntu0.16.04.1","1.18.3-0ubuntu0.16.04.1","1.18.5-0ubuntu0.16.04.1","1.19.4-0ubuntu0.16.04.1","1.20.4-0ubuntu0.16.04.1","1.21.5-0ubuntu0.16.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"liboxideqt-qmlplugin","binary_version":"1.21.5-0ubuntu0.16.04.1"},{"binary_name":"liboxideqtcore0","binary_version":"1.21.5-0ubuntu0.16.04.1"},{"binary_name":"liboxideqtquick0","binary_version":"1.21.5-0ubuntu0.16.04.1"},{"binary_name":"oxideqt-codecs","binary_version":"1.21.5-0ubuntu0.16.04.1"},{"binary_name":"oxideqt-codecs-extra","binary_version":"1.21.5-0ubuntu0.16.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-6548.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:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
