Buffer overflows in PL/SQL module 3.0.9.8.2 in Oracle 9i Application Server 1.0.2.x allow remote attackers to cause a denial of service or execute arbitrary code via (1) a long help page request without a dadname, which overflows the resulting HTTP Location header, (2) a long HTTP request to the plsql module, (3) a long password in the HTTP Authorization, (4) a long Access Descriptor (DAD) password in the addadd form, or (5) a long cache directory name.
