CVE-2016-10739 (GCVE-0-2016-10739)

Vulnerability from cvelistv5 – Published: 2019-01-21 19:00 – Updated: 2024-08-06 03:30

Summary

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.
