Description Murray McAllister 2014-07-17 09:12:54 UTC

The following flaw has been fixed in the Apache HTTP Server:

"A resource consumption flaw was found in mod_deflate. If request body decompression was configured (using the "DEFLATE" input filter), a remote attacker could cause the server to consume significant memory and/or CPU resources. The use of request body decompression is not a common configuration."
