Format string vulnerability in the emf_multipart_encrypted function in mail/em-format.c in Evolution 2.12.3 and earlier allows remote attackers to execute arbitrary code via a crafted encrypted message, as demonstrated using the Version field.
Evolution 2.8.1 and earlier does not properly use the --status-fd argument when invoking GnuPG, which prevents Evolution from visually distinguishing between signed and unsigned portions of OpenPGP messages with multiple components, which allows remote attackers to forge the contents of a message without detection.
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.
Integer overflow in camel-lock-helper in Evolution 2.0.2 and earlier allows local users or remote malicious POP3 servers to execute arbitrary code via a length value of -1, which leads to a zero byte memory allocation and a buffer overflow.
