{"id":"USN-4167-1","summary":"samba vulnerabilities","details":"Michael Hanselmann discovered that the Samba client code incorrectly\nhandled path separators. If a user were tricked into connecting to a\nmalicious server, a remote attacker could use this issue to cause the\nclient to access local pathnames instead of network pathnames.\n(CVE-2019-10218)\n\nSimon Fonteneau and Björn Baumbach discovered that Samba incorrectly\nhandled the check password script. This issue could possibly bypass custom\npassword complexity checks, contrary to expectations. This issue only\naffected Ubuntu 18.04 LTS, Ubuntu 19.04, and Ubuntu 19.10. (CVE-2019-14833)\n\nAdam Xu discovered that Samba incorrectly handled the dirsync LDAP control.\nA remote attacker with \"get changes\" permissions could possibly use this\nissue to cause Samba to crash, resulting in a denial of service.\n(CVE-2019-14847)\n","modified":"2026-04-22T10:05:02.599871Z","published":"2019-10-29T12:15:30Z","related":["UBUNTU-CVE-2019-10218","UBUNTU-CVE-2019-14833","UBUNTU-CVE-2019-14847"],"upstream":["CVE-2019-10218","CVE-2019-14833","CVE-2019-14847","UBUNTU-CVE-2019-10218","UBUNTU-CVE-2019-14833","UBUNTU-CVE-2019-14847"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4167-1"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-10218"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-14833"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-14847"}],"affected":[{"package":{"name":"samba","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/samba@2:4.3.11+dfsg-0ubuntu0.16.04.23?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.3.11+dfsg-0ubuntu0.16.04.23"}]}],"versions":["2:4.1.17+dfsg-4ubuntu2","2:4.1.20+dfsg-1ubuntu1","2:4.1.20+dfsg-1ubuntu2","2:4.1.20+dfsg-1ubuntu3","2:4.1.20+dfsg-1ubuntu5","2:4.3.3+dfsg-1ubuntu1","2:4.3.3+dfsg-1ubuntu2","2:4.3.3+dfsg-1ubuntu3","2:4.3.6+dfsg-1ubuntu1","2:4.3.8+dfsg-0ubuntu1","2:4.3.9+dfsg-0ubuntu0.16.04.1","2:4.3.9+dfsg-0ubuntu0.16.04.2","2:4.3.9+dfsg-0ubuntu0.16.04.3","2:4.3.11+dfsg-0ubuntu0.16.04.1","2:4.3.11+dfsg-0ubuntu0.16.04.3","2:4.3.11+dfsg-0ubuntu0.16.04.5","2:4.3.11+dfsg-0ubuntu0.16.04.6","2:4.3.11+dfsg-0ubuntu0.16.04.7","2:4.3.11+dfsg-0ubuntu0.16.04.8","2:4.3.11+dfsg-0ubuntu0.16.04.9","2:4.3.11+dfsg-0ubuntu0.16.04.10","2:4.3.11+dfsg-0ubuntu0.16.04.11","2:4.3.11+dfsg-0ubuntu0.16.04.12","2:4.3.11+dfsg-0ubuntu0.16.04.13","2:4.3.11+dfsg-0ubuntu0.16.04.15","2:4.3.11+dfsg-0ubuntu0.16.04.16","2:4.3.11+dfsg-0ubuntu0.16.04.17","2:4.3.11+dfsg-0ubuntu0.16.04.18","2:4.3.11+dfsg-0ubuntu0.16.04.19","2:4.3.11+dfsg-0ubuntu0.16.04.20","2:4.3.11+dfsg-0ubuntu0.16.04.21"],"ecosystem_specific":{"binaries":[{"binary_name":"ctdb","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23","binary_name":"libnss-winbind"},{"binary_name":"libpam-winbind","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"libparse-pidl-perl","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"libsmbclient","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"libwbclient0","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"python-samba","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"registry-tools","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"samba","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"samba-common","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23","binary_name":"samba-common-bin"},{"binary_name":"samba-dsdb-modules","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"samba-libs","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"samba-testsuite","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"samba-vfs-modules","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"smbclient","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"},{"binary_name":"winbind","binary_version":"2:4.3.11+dfsg-0ubuntu0.16.04.23"}],"availability":"No
