TechGlyphs Editor A highly critical vulnerability has been uncovered in the GNU C Library (glibc), a key component of most Linux distributions, that leaves nearly all Linux machines, thousands of apps and electronic devices vulnerable to hackers. GNU C Library (glibc) is a collection of open source code that powers thousands of standalone apps and most Linux distributions, including those distributed to routers and other types of hardware.The flaw can be exploited when an affected device or app make queries to a malicious DNS server that returns too much information to a lookup request and floods the program's memory with code. This code then compromises the vulnerable application or device and tries to take over the control over the whole system. It is possible to inject the domain name into server log files, which when resolved will trigger remote code execution. An SSH (Secure Shell) client connecting to a server could also be compromised. However, an attacker need to bypass sev
