Synopsis

The remote machine is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has dovecot packages installed that are affected by a vulnerability:

- In Dovecot before 2.2.36.4 and 2.3.x before 2.3.7.2 (and Pigeonhole before 0.5.7.2), protocol processing can fail for quoted strings. This occurs because '\0' characters are mishandled, and can lead to out-of-bounds writes and remote code execution. (CVE-2019-11500)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL dovecot packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
