Descriptions
Squid before 4.4, when SNMP is enabled, allows a denial of service (Memory Leak) via an SNMP packet.
Squid en versiones anteriores a la 4.4, cuando está habilitado SNMP, permite una denegación de servicio (fuga de memoria) mediante un paquete SNMP.

This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. It was discovered that Squid incorrectly handled the cachemgr.cgi web module. A remote attacker could possibly use this issue to conduct cross-site scripting attacks. Various other issues were also addressed.
