Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Information disclosure

EUVDB-ID: #VU32505

Risk: Low

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

CVE-ID: CVE-2014-5270

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate attackers to conduct key-extraction attacks by leveraging the ability to collect voltage data from exposed metal, a different vector than CVE-2013-4576.

Mitigation

Install update from vendor's website.

Vulnerable software versions

libgcrypt (Alpine package): 1.5.0-r0 - 1.5.3-r0
