CVE-2016-10739 is a vulnerability of currently unknown severity. In the GNU C Library (aka glibc or libc6) through 2.28, the getaddrinfo function would successfully parse a string that contained an IPv4 address followed by whitespace and arbitrary characters, which could lead applications to incorrectly assume that it had parsed a valid string, without the possibility of embedded HTTP headers or other potentially dangerous substrings.. EPSS estimates a 0.48% chance of exploitation in the next 30 days.
