1) Insufficient entropy in PRNG

EUVDB-ID: #VU11846

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-0016

CWE-ID: CWE-332 - Insufficient Entropy in PRNG

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the targets system.

The weakness exists due to improper update of the state of the OpenSSL pseudo-random number generator (PRNG), which causes subsequent children with the same process ID to use the same entropy pool, when using fork threading. A remote attacker can gain access to potentially sensitive information.

Mitigation

Update the affected packages.
net-misc/stunnel to version: 5.02

Vulnerable software versions

Gentoo Linux: All versions
