Linux “Ghost” Vulnerability
In case you are not already aware, there has been a Linux vulnerability discovered commonly known as “GHOST” which is a ‘buffer overflow’ bug affecting the gethostbyname() and gethostbyname2() function calls in the glibc library. Remote attackers can use this flaw to execute arbitrary code with the permissions of the user running the application. It could also perform an out-of-bounds array access, causing the process to crash and in some scenarios, this could allow a remote attacker to cause a persistent denial of servers.
