Risk: High
SCO has issued a maintenance pack for OpenServer. This fixes various vulnerabilities in Mozilla, zip, libpng, zlib, libtiff, bzip2, openssh, php, perl, gzip, CUPS, wu-ftpd, cdrecord and squid, which can be exploited to cause a DoS (Denial of Service), spoof the content of websites, gain knowledge of potentially sensitive information, conduct cross-site scripting attacks, bypass certain security restrictions, manipulate certain data, or compromise a user's system, and by malicious, local users to gain escalated privileges.
