Description

Samba version 4.0.0 up to 4.5.2 is vulnerable to privilege elevation due to incorrect handling of the PAC (Privilege Attribute Certificate) checksum. A remote, authenticated, attacker can cause the winbindd process to crash using a legitimate Kerberos ticket. A local service with access to the winbindd privileged pipe can cause winbindd to cache elevated access permissions.

Affected configurations

• samba samba (>= 4.0.0 < 4.3.13) • samba samba (>= 4.4.0 < 4.4.8) • samba samba (>= 4.5.0 < 4.5.3)
