Description: SCO has issued various updated network drivers to fix an older information disclosure vulnerability. The problem is that many ethernet NIC (Network Interface Card) device drivers pad frames with content from previous packets or kernel memory instead of using NULL-bytes. This may be exploited by malicious people to obtain potentially sensitive information by sending specially crafted packets to a vulnerable system. The vulnerability has been reported in Open UNIX 8.0.0 and UnixWare 7.1.3 and 7.1.1. Solution: Install latest packages. UnixWare 7.1.3: ftp://ftp.sco.com/pub/updates/UnixWare/CSSA-2003-SCO.21/nics.image UnixWare 7.1.1 (requires Maintaince Pack 3): ftp://ftp.sco.com/pub/updates/UnixWare/CSSA-2003-SCO.21/erg712090.pkg.Z Open UNIX 8.0.0 (requires Maintaince Pack 6): ftp://ftp.sco.com/pub/updates/OpenUNIX/CSSA-2003-SCO.21/erg712090.pkg.Z Original Advisory: ftp://ftp.sco.com/pub/updates/UnixWare/CSSA-2003-SCO.21/CSSA-2003-SCO.21.txt
