Remote Buffer Overflow Vulnerability in Sun RPC

Synopsis:

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
versions.

Impact:

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
protected networks

Affected Versions:

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.
