A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions.
