CVE-2013-4352

Status Candidate

Overview

The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger a missing hostname value.

Red Hat Security Advisory 2014-0921-01

Red Hat Security Advisory 2014-0921-01 - The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. 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 NULL pointer dereference flaw was found in the mod_cache httpd module. A malicious HTTP server could cause the httpd child process to crash when the Apache HTTP Server was used as a forward proxy with caching.
