GNOME Evolution 1.4

Format string vulnerability in Evolution 1.4 through 2.3.6.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the calendar entries such as task lists, which are not properly handled when the user selects the Calendars tab.

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.
