Official Description

Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST."

Source: NIST NVD / MITRE CVE Database

Attack Vector Analysis — CITED Relevance

The vulnerability can be exploited via the gethostbyname or gethostbyname2 functions. An attacker can craft malicious input that triggers a buffer overflow, leading to arbitrary code execution in the context of the application using these functions.
