CVE-2015-0253 medium priority: Ubuntu including 1 source packages (apache2), 5 status rows across 5 suites (precise, trusty, upstream, utopic, vivid): not-affected 4, released 1.
The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI.
