Oracle SYS_CONTEXT Procedure Buffer Overflow Vulnerability
A buffer overflow vulnerability was found in the SYS_CONTEXT procedure in
Oracle Database Server allowing a valid database user to execute arbitrary
* Oracle 9i Release 2 versions 220.127.116.11 up to and including 18.104.22.168
(Windows platform only)
* Oracle 9i Release 1
* Oracle 10g
The vulnerability can be exploited by any valid database user able to
execute SQL commands via SQL Plus. The buffer overflow can then be
exploited by calling the SYS_CONTEXT() function. As with all buffer
overflows the cause for the vulnerability is either no bounds checking or
a degenerate case leading to an overwrite of the buffer due to a
programming error when performing bounds checking.
