In uClibc and uClibc-ng before 1.0.39 incorrect handling of special characters in domain names returned by DNS servers via gethostbyname getaddrinfo gethostbyaddr and getnameinfo can lead to output of wrong hostnames (leading to domain hijacking) or injection into applications (leading to remote code execution XSS applications crashes etc.). In other words a validation step which is expected in any stub resolver does not occur.
