{"id":"CVE-2018-19857","details":"The CAF demuxer in modules/demux/caf.c in VideoLAN VLC media player 3.0.4 may read memory from an uninitialized pointer when processing magic cookies in CAF files, because a ReadKukiChunk() cast converts a return value to an unsigned int even if that value is negative. This could result in a denial of service and/or a potential infoleak.","modified":"2026-04-10T04:07:37.632494Z","published":"2018-12-05T11:29:05.827Z","related":["openSUSE-SU-2019:1840-1","openSUSE-SU-2019:1897-1","openSUSE-SU-2019:1909-1","openSUSE-SU-2019:2015-1","openSUSE-SU-2024:11502-1"],"references":[{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00005.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00037.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00040.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00081.html"},{"type":"WEB","url":"https://git.videolan.org/?p=vlc.git%3Ba=commit%3Bh=0cc5ea748ee5ff7705dde61ab15dff8f58be39d0"},{"type":"WEB","url":"https://usn.ubuntu.com/4074-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2019/dsa-4366"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106130"},{"type":"EVIDENCE","url":"https://dyntopia.com/advisories/013-vlc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/videolan/vlc-3.0","events":[{"introduced":"0"},{"last_affected":"f615db63323905da6bdff735c1c717e33e3024fa"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"3.0.4"}]}}],"versions":["0.9.0","0.9.0-test0","0.9.0-test1","0.9.0-test2","0.9.0-test3","1.0.0-pre1","1.0.0-pre2","1.0.0-rc1","1.1.0-ff","1.1.0-pre1","1.2.0-pre1","1.3.0-git","2.1.0-git","2.2.0-git","3.0.0","3.0.0-1","3.0.0-2","3.0.0-git","3.0.0-rc1","3.0.0-rc2","3.0.0-rc3","3.0.0-rc4","3.0.0-rc5","3.0.0-rc6","3.0.0-rc7","3.0.0-rc8","3.0.0.1","3.0.1","3.0.2","3.0.3","3.0.3-1","3.0.4","svn-trunk"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"9.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-19857.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:N/A:H"}]}
