Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU33952

Risk: High

CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]

CVE-ID: CVE-2012-1182

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The RPC code generator in Samba 3.x before 3.4.16, 3.5.x before 3.5.14, and 3.6.x before 3.6.4 does not implement validation of an array length in a manner consistent with validation of array memory allocation, which allows remote attackers to execute arbitrary code via a crafted RPC call.

Mitigation

Install update from vendor's website.

2) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU32799

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2012-2111

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote #AU# to read and manipulate data.

The (1) CreateAccount, (2) OpenAccount, (3) AddAccountRights, and (4) RemoveAccountRights LSA RPC procedures in smbd in Samba 3.4.x before 3.4.17, 3.5.x before 3.5.15, and 3.6.x before 3.6.5 do not properly restrict modifications to the privileges database, which allows remote authenticated users to obtain the "take ownership" privilege via an LSA connection.

Mitigation

Install update from vendor's website.
