Synopsis
The remote machine is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has dovecot packages installed that are affected by multiple vulnerabilities:- In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components. (CVE-2019-7524)
- It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users. (CVE-2019-3814)
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.See Also
