Stack Buffer Overflows – Old Exploits Never Die

Buffer overflows remain one of the most highly exploitable vulnerabilities on the Internet. Just last month (Feb 2016), researchers from Red Hat and Google discovered a bug in the GNU C Library a.k.a.  Glibc that made machines running the glibc package vulnerable to stack-based buffer overflow exploits.

The glibc package is found in several Linux distributions, including those running on servers as well as some routers and other network devices, so the potential scope of impact is quite extensive. Fortunately, a bug fix has already been released and hopefully the majority of the affected machines should have been patched by now. Nevertheless, it doesn’t change the fact that buffer overflows continue to be a threat to information security.
