The Mailer component in Evolution 2.26.1 and earlier uses world-readable permissions for the .evolution directory, and certain directories and files under .evolution/ related to local mail, which allows local users to obtain sensitive information by reading these files.
CVSS Severity (version 2.0):
Impact Subscore: 2.9
Exploitability Subscore: 3.9
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information
Official Statement from Red Hat (12/07/2009)
Red Hat does not consider this to be a security issue. By default, user home directories are created with mode 0700 permissions, which would not expose the ~/.evolution/ directory regardless of its own permissions.
If a user intentionally relaxes permissions on their home directory, they should be auditing all files and directories in order to not expose unwanted files to other local users.
