(MySQL: Two Denial of Service vulnerabilities)

    mu-b discovered a NULL pointer dereference in item_cmpfunc.cc when
    processing certain types of SQL requests. Sec Consult also discovered
    another NULL pointer dereference when sorting certain types of queries
    on the database metadata.
  
Impact :

    In both cases, a remote attacker could send a specially crafted SQL
    request to the server, possibly resulting in a server crash. Note that
    the attacker needs the ability to execute SELECT queries.
  
Workaround :

    There is no known workaround at this time."
