Introduction Server security vulnerabilities can expose key services and applications to attacks. One of these vulnerabilities is the GHOST vulnerability (CVE-2015-0235). This flaw was found in the GNU C Library (glibc) and impacts many Linux distributions. Since several essential services, such as SSH, Bash, and DNS-related applications, rely on glibc, it is crucial for system administrators to check if their servers are vulnerable and implement the necessary fixes. This article outlines how to check for the GHOST vulnerability and decide if your Linux server is at risk. On Linux servers, more than 60 binaries and major services, such as SSH, Nmap, and Bash, rely on the glibc libraries. A heap-based buffer overflow was found in __nss_hostname_digits_dots(), and an attacker could …
