CVE-2016-10739 MEDIUM

Published: 2019-01-21 | Last Modified: 2026-06-17 | Status: Modified

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.

Additional Descriptions (1)

En la biblioteca GNU C Library (también conocida como glibc o libc6) hasta la versión 2.28, la función getaddrinfo analiza exitosamente una cadena que contiene una dirección IPv4 seguida por un espacio en blanco y caracteres arbitrarios. Esto podría provocar que las aplicaciones asuman incorrectamente que han analizado una cadena válida, sin contemplar la posibilidad de que haya cabeceras HTTP embebidas u otras subcadenas potencialmente maliciosas.
