CVE-2014-9402 describes a denial-of-service vulnerability in the GNU C Library (glibc) affecting versions prior to 2.21, specifically within its nss_dns implementation of getnetbyname. This flaw allows remote attackers to trigger an infinite loop by sending a positive DNS answer while a network name is being processed, impacting various distributions including Canonical, GNU, and openSUSE. With a CVSS score of 7.8 (High), the vulnerability is easily exploitable over the network with low attack complexity, leading to a complete loss of availability. Despite its severity, there is no evidence of active exploitation, no public exploit code available, and minimal community discussion or media coverage, suggesting it is not currently a high-profile threat.
