GNOME Evolution before 3.2.3 allows user-assisted remote attackers to read arbitrary files via the attachment parameter to a mailto: URL, which attaches the file to the email.

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.

The camel component for Ximian Evolution 1.0.x and earlier does not verify certificates when it establishes a new SSL connection after previously verifying a certificate, which could allow remote attackers to monitor or modify sessions via a man-in-the-middle attack.

Ximian Evolution Mail User Agent 1.2.2 and earlier allows remote attackers to cause a denial of service (memory consumption) via a mail message that is uuencoded multiple times.

The handle_image function in mail-format.c for Ximian Evolution Mail User Agent 1.2.2 and earlier does not properly escape HTML characters, which allows remote attackers to inject arbitrary data and HTML via a MIME Content-ID header in a MIME-encoded image.

The try_uudecoding function in mail-format.c for Ximian Evolution Mail User Agent 1.2.2 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a malicious uuencoded (UUE) header, possibly triggering a heap-based buffer overflow.
