Description:
10
 
 Samba version 4.0.0 up to 4.5.2 is vulnerable to privilege elevation due to
11
 
 incorrect handling of the PAC (Privilege Attribute Certificate) checksum. A
12
 
 remote, authenticated, attacker can cause the winbindd process to crash
13
 
 using a legitimate Kerberos ticket. A local service with access to the
14
 
 winbindd privileged pipe can cause winbindd to cache elevated access
15
 
 permissions.

Ubuntu-Description: 
17
 
 Volker Lendecke discovered that Kerberos PAC validation implementation
18
 
 in Samba contained multiple vulnerabilities. An authenticated attacker
19
 
 could use this to cause a denial of service or gain administrative
20
 
 privileges.
