Description

Multiple memory leaks in the LDAP component in Fedora Directory Server 1.0 allow remote attackers to cause a denial of service (memory consumption) via invalid BER packets that trigger an error, which might prevent memory from being freed if it was allocated during the ber_scanf call, as demonstrated using the ProtoVer LDAP test suite.
