INFORMATION BULLETIN
Oracle9i Database Buffer Overflow Vulnerabilities
[VU# 819126, VU#240174, VU#846582, VU#399806]
March 8, 2004 19:00 GMT Number O-093
______________________________________________________________________________
PROBLEM: Oracle9i Database contains vulnerabilities in the following
areas:
(1) TIME_ZONE session parameter - This session parameter
specifies the local time zone displacement for the current
SQL session.
(2) NUMTOYMINTERVAL() function - This function is responsible
for handling date conversions.
(3) NUMTODSINTERVAL() function - This function is responsible
for handling date/time conversions.
(4) FROM_TZ() function - This function is responsible for
handling time stamp conversions.
SOFTWARE: Oracle 9i Database
DAMAGE: Execution of arbitrary code or accessing data with privilege of
the vulnerable process may occur if vulnerabilities are
exploited. Note that Oracle typically runs as System on Windows
and as the Oracle user on UNIX. By supplying a very long
character string to the vulnerable functions noted above, an
unauthorized user could overwrite a return address on the
stack, resulting in the ability to execute arbitrary code or
access data with the privileges of the vulnerable process.
SOLUTION: Upgrade to Oracle 9i Database Release 2, version 9.2.0.3.
______________________________________________________________________________
VULNERABILITY The risk is MEDIUM. An unauthorized user may execute arbitrary
ASSESSMENT: code or access data.
