Description

An issue was found in the 'namespace_from_uri' method of the ModPerl::RegistryCooker class. If a server implemented a mod_perl registry module using this method, a remote attacker requesting a carefully crafted URI can cause resource consumption, which could lead to a denial of service (CVE-2007-1349).
