CVE-2014-3493: The push_ascii function in smbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 a...

The push_ascii function in smbd in Samba 3.6.x before 3.6.24, 4.0.x before 4.0.19, and 4.1.x before 4.1.9 allows remote authenticated users to cause a denial of service (memory corruption and daemon crash) via an attempt to read a Unicode pathname without specifying use of Unicode, leading to a character-set conversion failure that triggers an invalid pointer dereference.

Security readout for executives and security teams

This vulnerability can let an authenticated SMB user crash Samba's smbd service on affected systems. The business impact is service disruption to file sharing, not documented code execution. The provided sources do not cite active exploitation or a CVSS score. Exposure is most likely on legacy Samba file servers still running the affected 3.6, 4.0, or 4.1 branches. Attack requires authenticated SMB access, so internal users, compromised accounts, or exposed authenticated file-sharing environments matter most. Prioritize remediation where Samba supports business-critical file shares or broad internal access. Treat internet-exposed or partner-accessible SMB as higher urgency. For isolated legacy systems with limited authenticated users, schedule upgrade through normal vulnerability management. Mitigation focus: Upgrade Samba beyond 3.6.24, 4.0.19, or 4.1.9 as applicable.; Apply distribution vendor updates from Red Hat, Fedora, Mandriva, Oracle Linux, or Gentoo where relevant.; Restrict SMB access to trusted networks and required authenticated users..
