CIAC Security Bulletin:

Oracle9i Database Buffer Overflow Vulnerabilities.

Detail
====== 

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.

               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
