Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Security Features

EUVDB-ID: #VU40410

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2016-3125

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

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

The mod_tls module in ProFTPD before 1.3.5b and 1.3.6 before 1.3.6rc2 does not properly handle the TLSDHParamFile directive, which might cause a weaker than intended Diffie-Hellman (DH) key to be used and consequently allow attackers to have unspecified impact via unknown vectors.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 5

proftpd: before 1.3.3g-6.el5
