Multiple format string vulnerabilities in Evolution 1.5 through 2.3.6.1 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) full vCard data, (2) contact data from remote LDAP servers, or (3) task list data from remote servers.

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.

Evolution 2.2.x and 2.3.x in GNOME 2.7 and 2.8, when "load images if sender in addressbook" is enabled, allows remote attackers to cause a denial of service (persistent crash) via a crafted "From" header that triggers an assert error in camel-internet-address.c when a null pointer is used.

The cairo library (libcairo), as used in GNOME Evolution and possibly other products, allows remote attackers to cause a denial of service (persistent client crash) via an attached text file that contains "Content-Disposition: inline" in the header, and a very long line in the body, which causes the client to repeatedly crash until the e-mail message is manually removed, possibly due to a buffer overflow, as demonstrated using an XML attachment.
