DNS: GNU C Library glibc getanswer_r Buffer Overflow
This signature detects attempts to exploit a code execution vulnerability in GNU C Library. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the targeted daemon.
Extended Description
Buffer overflow in the gethostbyname_r and other unspecified NSS functions in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response, which triggers a call with a misaligned buffer.
