su Security Patch
---------------------------------------------------------------------------

I.   Description

        Several security holes were found in the "su" program along with
        the iaf library.

II.  Impact

        Without these patches, unauthorized users may gain privileges.

III. Releases

        This SSE contains binaries for:

        UnixWare 2.1.3
        UnixWare 7.0.0 through 7.1.1

IV.  Solution

SCO is providing an interim patch to address this issue in the form of a
System Security Enhancement (SSE) package.

SSE039 contains replacement binaries for each system type, and is
available for Internet download via anonymous ftp, and from the SCOFORUM
on Compuserve.

You can download the SSE package as follows:
