Summary
samba vulnerabilities
Details

Michael Hanselmann discovered that the Samba client code incorrectly handled path separators. If a user were tricked into connecting to a malicious server, a remote attacker could use this issue to cause the client to access local pathnames instead of network pathnames. (CVE-2019-10218)

Simon Fonteneau and Björn Baumbach discovered that Samba incorrectly handled the check password script. This issue could possibly bypass custom password complexity checks, contrary to expectations. This issue only affected Ubuntu 18.04 LTS, Ubuntu 19.04, and Ubuntu 19.10. (CVE-2019-14833)

Adam Xu discovered that Samba incorrectly handled the dirsync LDAP control. A remote attacker with "get changes" permissions could possibly use this issue to cause Samba to crash, resulting in a denial of service. (CVE-2019-14847)
