CVE-2016-10739

Published: 21 January 2019

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.

Notes

glibc uses this internally to parse config files, fixing this
may introduce unwanted regressions and changes in behaviour
