Internet Security Systems Security Brief
July 31, 2002
Remote Buffer Overflow Vulnerability in Sun RPC
Internet Security Systems (ISS) X-Force has discovered a buffer overflow
in the xdr_array filter primitive. This function is a part of the Sun RPC
library, and it is used in multiple RPC services. Any native or third party
software that uses the xdr_array function may be vulnerable. Vulnerable RPC
services are installed and enabled by default on the affected software
The buffer overflow vulnerability can allow remote attackers to execute
arbitrary commands on a target system with superuser privileges. Attackers
pose the most serious risk when attacking unprotected networks, or improperly
Sun Microsystems Solaris 2.5.1
Sun Microsystems Solaris 2.6
Sun Microsystems Solaris 7
Sun Microsystems Solaris 8
Sun Microsystems Solaris 9
Note: The versions above were tested and found to be vulnerable. Additional
commercial and open-source Unix operating systems use implementations of Sun
RPC, and may also be vulnerable.
