Subject:                UnixWare 7.1.3 UnixWare 7.1.4 : uidadmin Buffer 
Overflow Vulnerability
Advisory number:        SCOSA-2005.54

1. Problem Description

        Local exploitation of a buffer overflow vulnerability in the
        uidadmin binary allows attackers to gain root privileges.

        Successful exploitation of this vulnerability requires that user
        have  local access to the system. This would allow the user to
        gain superuser  privileges.

        The Common Vulnerabilities and Exposures project (cve.mitre.org)
        has assigned the name CVE-2005-3903 to this issue.
