1) Cryptographic issues

EUVDB-ID: #VU32623

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2013-4476

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.

Samba 4.0.x before 4.0.11 and 4.1.x before 4.1.1, when LDAP or HTTP is provided over SSL, uses world-readable permissions for a private key, which allows local users to obtain sensitive information by reading the key file, as demonstrated by access to the local filesystem on an AD domain controller.

Mitigation

Install update from vendor's website.

Vulnerable software versions

samba (Alpine package): 3.6.13-r0 - 3.6.19-r1
