Description: Ulf Harnhammar has reported some vulnerabilities in Evolution, which can be exploited by malicious people to compromise a vulnerable system.
1) A format string error when displaying full vCard information attached to an e-mail message can be exploited to execute arbitrary code.
Successful exploitation requires that the user clicks on "Show Full vCard" or saves the vCard to an address book and then views it under the "Contacts" tab.
2) A format string error exists when displaying specially crafted contact data retrieved from an LDAP server.
3) A format string error exists when displaying specially crafted task list data retrieved from remote servers and when the user saves the task list data under the "Calendars" tab.
The vulnerabilities have been reported in versions 1.5 through 2.3.6.1.
Solution: The vulnerabilities have reportedly been fixed in 2.3.7 (unstable).
