glibc: getaddrinfo should reject IP addresses with trailing characters
Published Jan 21, 2019

MEDIUMCVSS 3.0
EPSS 0.48%
Description
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.
