How to Detect Exploits of the GHOST Buffer Overflow Vulnerability

The GHOST vulnerability is a buffer overflow condition that can be easily exploited locally and remotely, which makes it extremely dangerous. This vulnerability is named after the GetHOSTbyname function involved in the exploit. Attackers utilize buffer overflow vulnerabilities like this one by...

glibc 'stdio-common/vfscanf.c' buffer overflow vulnerability
