Buffer overflow in Evolution 2.22.1, when the ITip Formatter plugin is disabled, allows remote attackers to execute arbitrary code via a long timezone string in an iCalendar attachment.
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.
