CVE-2019-10218: Fedoraproject Fedora

Medium severity, CVSS 6.5. EPSS: 3.4% chance of exploitation in the next 30 days.

A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user.

Affected products

• Fedoraproject Fedora: version 29 only; version 31 only
• Samba Samba: before 4.9.15 (fixed in 4.9.15); from 4.10.0, before 4.10.10 (fixed in 4.10.10); from 4.11.0, before 4.11.2 (fixed in 4.11.2)
