Subject:                UnixWare 7.1.3 UnixWare 7.1.4 : LibXpm Integer Overflow 
Vulnerability
Advisory number:        SCOSA-2005.57
Issue date:             2005 December 14
Cross reference:        fz533161
                        CVE-2005-0605

______________________________________________________________________________


1. Problem Description

        An integer overflow vulnerability in libXpm can be exploited by
        a remote user to cause arbitrary code to be executed.

        The 'scan.c' code does not properly validate user-supplied data
        contained in image files. A remote user can create a specially
        crafted image file that, when processed by the target user or
        application, will trigger the overflow and execute arbitrary
        code.

        The Common Vulnerabilities and Exposures project (cve.mitre.org)
        has assigned the name CVE-2005-0605 to this issue.
