CVE-2014-0118

La función deflate_in_filter en mod_deflate.c en el módulo mod_deflate en Apache HTTP Server anterior a 2.4.10, cuando la descompresión del cuerpo de una solicitud está habilitada, permite a atacantes remotos causar una denegación de servicio (consumo de recursos) a través de datos de solicitudes manipulados que descomprime a un tamaño mucho más grande.

A denial of service flaw was found in the way httpd's mod_deflate module handled request body decompression (configured via the "DEFLATE" input filter). A remote attacker able to send a request whose body would be decompressed could use this flaw to consume an excessive amount of system memory and CPU on the target system.

A race condition flaw, leading to heap-based buffer overflows, was found in the mod_status httpd module. A remote attacker able to access a status page served by mod_status on a server using a threaded Multi-Processing Module could send a specially crafted request that would cause the httpd child process to crash or, possibly, allow the attacker to execute arbitrary code with the privileges of the apache user. A denial of service flaw was found in the way httpd's mod_deflate module handled request body decompression (configured via the DEFLATE input filter. A remote attacker able to send a request whose body would be decompressed could use this flaw to consume an excessive amount of system memory and CPU on the target system. A denial of service flaw was found in the way httpd's mod_cgid module executed CGI scripts that did not read data from the standard input. A remote attacker could submit a specially crafted request that would cause the httpd child process to hang indefinitely.
