Descriptions

Due to incorrect string termination, Squid cachemgr.cgi 4.0 through 4.7 may access unallocated memory. On systems with memory access protections, this can cause the CGI process to terminate unexpectedly, resulting in a denial of service for all clients using it.

Debido a una terminaciĆ³n de cadena incorrecta, el archivo cachemgr.cgi de Squid versiones 4.0 hasta 4.7 puede acceder a la memoria no asignada. En sistemas con protecciones de acceso a memoria, esto puede causar que el proceso CGI finalice inesperadamente, resultando en una denegaciĆ³n de servicio para todos los clientes que lo usan.
