{"id":"UBUNTU-CVE-2019-9719","details":"** DISPUTED ** A stack-based buffer overflow in the subtitle decoder in Libav 12.3 allows attackers to corrupt the stack via a crafted video file in Matroska format, because srt_to_ass in libavcodec/srtdec.c misuses snprintf. NOTE: Third parties dispute that this is a vulnerability because “no evidence of a vulnerability is provided” and only “a generic warning from a static code analysis” is provided.","modified":"2019-09-19T21:15:00Z","published":"2019-09-19T21:15:00Z","withdrawn":"2025-06-23T15:53:21Z","references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-9719"},{"type":"REPORT","url":"https://github.com/libav/libav/blob/df744e3cf66548c9167ea857104a29d2ea92819e/libavcodec/srtdec.c#L113"},{"type":"REPORT","url":"https://github.com/libav/libav/commits/master/libavcodec/srtdec.c"},{"type":"REPORT","url":"https://lgtm.com/projects/g/libav/libav/snapshot/f5f553ca3bdca0c97dd08bbf002f0d8cb193788b/files/libavcodec/srtdec.c?sort=name&dir=ASC&mode=heatmap#xeec693aa6d85853b:1"},{"type":"REPORT","url":"https://lgtm.com/security/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-9719"}],"affected":[{"package":{"name":"gst-libav1.0","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/gst-libav1.0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.0-1","1.6.0-2","1.6.1-1","1.6.2-1","1.7.1-1","1.7.2-1","1.7.90-1","1.8.0-1","1.8.1-1~ubuntu1","1.8.2-1~ubuntu1","1.8.3-1ubuntu0.1","1.8.3-1ubuntu0.2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"vice","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/vice"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.dfsg+2.4.20-1","2.4.dfsg+2.4.25-1ubuntu1","2.4.dfsg+2.4.25-2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"gst-libav1.0","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/gst-libav1.0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.12.2-1","1.12.3-1","1.12.4-1","1.13.91-1","1.14.0-1","1.14.1-1~ubuntu18.04.1","1.14.4-0ubuntu1~ubuntu18.04.1","1.14.5-0ubuntu1~18.04.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"qtwebengine-opensource-src","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/qtwebengine-opensource-src"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.9.1+dfsg-4","5.9.1+dfsg-4ubuntu1","5.9.2+dfsg-2ubuntu1","5.9.3+dfsg-0ubuntu1","5.9.4+dfsg-0ubuntu1","5.9.5+dfsg-0ubuntu2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"vice","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/vice"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.0.dfsg-1","3.1.0.dfsg1-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"gst-libav1.0","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/gst-libav1.0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.16.1-1","1.16.2-1","1.16.2-2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"qtwebengine-opensource-src","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/qtwebengine-opensource-src"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.12.4+dfsg-1ubuntu1","5.12.4+dfsg-1ubuntu3","5.12.5+dfsg-3ubuntu1","5.12.5+dfsg-6ubuntu2","5.12.5+dfsg-7","5.12.5+dfsg-7build1","5.12.8+dfsg-0ubuntu1","5.12.8+dfsg-0ubuntu1.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"vice","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/vice"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.3.0.dfsg-2build1","3.4.0.dfsg-1","3.4.0.dfsg-1build1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"gst-libav1.0","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/gst-libav1.0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.18.5-1","1.20.0-1","1.20.1-1","1.20.3-0ubuntu1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"qtwebengine-opensource-src","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/qtwebengine-opensource-src"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.15.6+dfsg-1","5.15.6+dfsg-2","5.15.7+dfsg-2","5.15.8+dfsg-1","5.15.8+dfsg-1build1","5.15.8+dfsg-1build2","5.15.8+dfsg-2","5.15.9+dfsg-1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-9719.json"}},{"package":{"name":"vice","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu
