CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:S/C:N/I:N/A:P

Remote Banner Unreliable
Solution Type:
Vendor Patch
Summary:
Cyrus IMAP is prone to a denial of service (DoS) vulnerability.
Detection Method:
Checks if a vulnerable version is present on the target host.
Technical Details:
Remote authenticated users could bypass intended access restrictions
on certain server annotations. Additionally, a long-standing bug in replication did not allow
server annotations to be replicated. Combining these two bugs, a remote authenticated user could
stall replication, requiring administrator intervention.
Affected Versions:
Cyrus IMAP prior to version 3.2.7 and version 3.3.x through 3.4.0.
Recommendations:
Update to version 3.2.7, 3.4.1 or later.

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
