Descriptions
The send_dg function in resolv/res_send.c in GNU C Library (aka glibc or libc6) before 2.20 does not properly reuse file descriptors, which allows remote attackers to send DNS queries to unintended locations via a large number of requests that trigger a call to the getaddrinfo function.
La función send_dg en resolv/res_send.c en GNU C Library (también conocido como glibc o libc6) en versiones anteriores a 2.20 no reutiliza adecuadamente descriptores de fichero, lo que permite a atacantes remotos mandar consultas DNS a ubicaciones no intencionadas a través de un gran número de peticiones que desencadenan una llamada a la función getaddrinfo.
It was discovered that, under certain circumstances, glibc's getaddrinfo() function would send DNS queries to random file descriptors. An attacker could potentially use this flaw to send DNS queries to unintended recipients, resulting in information disclosure or data loss due to the application encountering corrupted data.
Many Moxa devices suffer from command injection, cross site scripting, and outdated software vulnerabilities.
