CVE-2014-9295
CVSS v2.0
7.5
High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
NTP versions prior to 4.2.8
Description
The issue is related to multiple stack-based buffer overflows in the ntpd service, which can be exploited by remote attackers to execute arbitrary code via crafted packets. This is related to the
crypto recv function when the Autokey Authentication feature is used, the ctl putdata function, and the configure function. The vulnerability can be exploited remotely, potentially leading to disruption of confidentiality, integrity, and availability of protected information.Recommendations
For versions prior to 4.2.8, update to version 4.2.8 or later to resolve the issue. As a temporary workaround, consider disabling the
crypto recv function when the Autokey Authentication feature is used, the ctl putdata function, and the configure function until a patch is available. Restrict access to the vulnerable ntpd service to minimize the risk of exploitation. Avoid using the vulnerable functions and features in the affected API endpoints until the issue is resolved.Exploit
