Evolution 2.0.3 allows remote attackers to cause a denial of service (application crash or hang) via crafted messages, possibly involving charsets in attachment filenames.

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.

The IMAP Client for Evolution 1.2.4 allows remote malicious IMAP servers to cause a denial of service and possibly execute arbitrary code via certain large literal size values that cause either integer signedness errors or integer overflow errors.

The IMAP Client for Sylpheed 0.8.11 allows remote malicious IMAP servers to cause a denial of service (crash) via certain large literal size values that cause either integer signedness errors or integer overflow errors.

The camel component for Ximian Evolution 1.0.x and earlier does not verify certificates when it establishes a new SSL connection after previously verifying a certificate, which could allow remote attackers to monitor or modify sessions via a man-in-the-middle attack.

The handleimage function in mail-format.c for Ximian Evolution Mail User Agent 1.2.2 and earlier does not properly escape HTML characters, which allows remote attackers to inject arbitrary data and HTML via a MIME Content-ID header in a MIME-encoded image.

The tryuudecoding function in mail-format.c for Ximian Evolution Mail User Agent 1.2.2 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a malicious uuencoded (UUE) header, possibly triggering a heap-based buffer overflow.

Ximian Evolution Mail User Agent 1.2.2 and earlier allows remote attackers to cause a denial of service (memory consumption) via a mail message that is uuencoded multiple times.

Evolution 1.0.3 and 1.0.4 allows remote attackers to cause a denial of service (memory consumption and crash) via an email with a malformed MIME header.
