       Oracle Buffer Overflow in Net Services for Oracle Database Server
                           [Oracle Secutity Alert 54]

April 30, 2003 16:00 GMT                                          Number N-085
PROBLEM:       A potential buffer overflow vulnerability has been discovered 
               in Oracle Net Services for the Oracle Database server. 
PLATFORM:      Oracle9/Release 2 
               Oracle9/Release 1 
               Oracle8/(8.1.x  all releases) 
               Oracle8 (8.0.x  all releases) 
               Oracle7 Release 7.3.x 
DAMAGE:        Exploiting this buffer overflow could lead to execution of 
               arbitrary code or result in a Denial of Service attack. 
SOLUTION:      Apply available patches. 
VULNERABILITY  The risk is MEDIUM. Unless the Oracle Database is connected 
ASSESSMENT:    directly to the Internet a remote exploit is unlikely. This 
               vulnerability is susceptible to an insider attack originated on 
               the corporate Intranet.
