CVE ID: CVE-2014-9984
Severity: CRITICAL
CVSS Score: 9.8
The GNU C Library, known commonly as glibc, is a fundamental component that powers a wide range of software in numerous systems, including Linux distributions. Among its various functionalities, glibc provides the nscd (Name Service Cache Daemon), which is essential for optimizing system performance by caching queries to the name service. However, a critical vulnerability identified as CVE-2014-9984 has surfaced, posing significant risks.
This vulnerability resides in the handling of netgroup requests by nscd before version 2.20. It arises due to a miscalculation in the size of an internal buffer, which can lead to a daemon crash or, more alarmingly, code execution with the privileges of the nscd user. Given its high CVSS score of 9.8, the impact of this security flaw is severe, meriting immediate attention and action by system administrators and users of affected systems.
The software affected by CVE-2014-9984 is the GNU C Library, particularly its nscd component. nscd's primary purpose is to speed up consecutive accesses to the same name service data by caching the outcomes of previous lookups. This caching mechanism, widely implemented in various Linux distributions, greatly enhances performance but, due to this vulnerability, can become a vector for potential exploits.
Addressing this vulnerability is paramount for maintaining system security and integrity. Patch management is a critical aspect of modern IT operations, especially in environments where Linux servers are prevalent. Timely application of patches ensures that vulnerabilities such as CVE-2014-9984 are mitigated before they can be exploited by attackers.
