A vulnerability has been found and corrected in ASF APR: tables/apr_hash.c in the Apache Portable Runtime library through 1.4.5 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service via crafted input to an application that maintains a hash table . APR has been upgraded to the latest version which holds many improvments over the previous versions and is not vulnerable to this issue.
