No Ip · No-Ip Duc · CVE-2008-5297
**Name of the Vulnerable Software and Affected Versions**
No-IP DUC version 2.1.7 and earlier
**Description**
The issue is related to a buffer overflow that allows remote HTTP servers to execute arbitrary code via a crafted response to a DNS update request. This is due to a missing length check in the `GetNextLine` function. Additionally, there are multiple vulnerabilities in the No-IP package that can lead to breaches of confidentiality, integrity, and availability of protected information, and these can be exploited remotely.
**Recommendations**
For No-IP DUC version 2.1.7 and earlier, consider disabling the `GetNextLine` function as a temporary workaround until a patch is available. Restrict access to the No-IP package to minimize the risk of exploitation. Avoid using the No-IP package for DNS updates until the issue is resolved.
