A highly critical vulnerability has been found in glibc, the GNU C library, which affects all Linux systems on glibc version 2.2 dating back to the year 2000. The vulnerability, with CVE-2015-0235, has already been nicknamed GHOST because of its relation to the _gethostbyname function. Read More.
It affects virtually all Linux-based software that perform domain name resolution. It also affects Linux programs written in Python, Ruby, and most other languages because they also rely on glibc. As a result, most Linux systems should be presumed vulnerable. Attackers can use this vulnerability to execute code and remotely gain control of Linux machines without having any credentials.
