Description

This security bulletin contains information about 1 security vulnerability.


1) Improper Certificate Validation (CVE-ID: CVE-2020-24661)

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

GNOME Geary before 3.36.3 mishandles pinned TLS certificate verification for IMAP and SMTP services using invalid TLS certificates (e.g., self-signed certificates) when the client system is not configured to use a system-provided PKCS#11 store. This allows a meddler in the middle to present a different invalid certificate to intercept incoming and outgoing mail.
