Summary

dn2ancestor in the LDAP component in Fedora Directory Server 1.0 allows remote attackers to cause a denial of service (CPU and memory consumption) via a ModDN operation with a DN that contains a large number of "," (comma) characters, which results in a large amount of recursion, as demonstrated using the ProtoVer LDAP test suite.
