| Package | Affected versions | Patched versions |
|---|---|---|
| dovecot | ≥ 2.3.9, < 2.3.9.3 | 2.3.9.3 |
The IMAP and LMTP components in Dovecot 2.3.9 before 2.3.9.3 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.
