Oracle, the giant enterprise database company - and, of course, owner of the erstwhile Sun Microsystems - has just published an out-of-band security update. This is only the fifth time Oracle has issued an alert outside its routine quarterly patch cycle since introducing its own version of Patch Tuesday at the start of 2005.
This security alert addresses the security issue CVE-2011-3192, a denial of service vulnerability in Apache HTTPD, which is applicable to Oracle HTTP Server products based on Apache 2.0 or 2.2. This vulnerability may be remotely exploitable without authentication, i.e. it may be exploited over a network without the need for a username and password. A remote user can exploit this vulnerability to impact the availability of un-patched systems.
