LIN1018-6259 : Security Advisory - gnutls - CVE-2020-13777

Created: Jun 4, 2020    Updated: Jun 21, 2020
Resolved Date: Jun 21, 2020
Found In Version: 10.18.44.1
Severity: Standard
Applicable for: Wind River Linux LTS 18
Component/s: Userspace

Description

GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application.
