"A security vulnerability was discovered in the Dovecot email server.
When reading FTS headers from the Dovecot index, the input buffer size
is not bounds-checked. An attacker with the ability to modify dovecot
indexes, can take advantage of this flaw for privilege escalation or
the execution of arbitrary code with the permissions of the dovecot
user. Only installations using the FTS plugins are affected.

For Debian 8 'Jessie', this problem has been fixed in version
1:2.2.13-12~deb8u6.

We recommend that you upgrade your dovecot packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
