EUVDB-ID: #VU12732

Risk: Low

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-9234

CWE-ID: CWE-320 - Key Management Errors

Exploit availability: No

Description

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

The weakness exists due to missing enforcement of a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey. A remote attacker can gain access to potentially sensitive information.

Mitigation

Update the affected package gpg2 to the latest version.
