=========================================================================== SCO Security Bulletin 99.16 27th October 1999 Multiple security holes found in FTP daemon software. --------------------------------------------------------------------------- I. Description Recently, CERT issued CA-99.13, an advisory that points out security vulnerabilities in FTP daemon software used by SCO. II. Impact Without SSE036, OpenServer versions 5.0.0 to 5.0.5 servers are vulnerable to remote network-based security compromises. III. Releases SSE036 only contains a replacement binary for OpenServer versions 5.0.0 5.0.5. For other SCO operating systems, please check the sco security website: http://www.sco.com/security. IV.
