By sending multiple specially-crafted HTTP POST requests to an affected application containing conflicting hash key values, a remote attacker could exploit this vulnerability to cause the consumption of CPU resources.

Apache Portable Runtime (APR) is vulnerable to a denial of service, caused by an error in the aprfnmatch() function when processing specific patterns with the "" wildcard.
