Dovecot is prone to multiple vulnerabilities.

Technical Details:
The following vulnerabilities exist: - The IMAP and LMTP components in Dovecot mishandle snippet generation when many characters must be read to compute the snippet and a trailing > character exists. This causes a denial of service in which the recipient cannot read all of their messages. - lib-smtp in submission-login and lmtp in Dovecot mishandles truncated UTF-8 data in command parameters.

Successful exploitation would cause various system processes to be exhausted, leading into a denial of service and CPU resource exhaustion, or cause the mailbox to be permanently unaccessible.

Detection Method:
Checks if a vulnerable version is present on the target host.

Affected Versions:
Dovecot versions 2.3.9 before

Update to version or later.
